isSamePrecedence indicates whether the precedence of the input operator is the same as the precedence of the (possible) operation represented in the i

isStrictRFC3339 reports whether s matches strictRFC3339Pattern, hand-rolled to keep the conversion path off the regexp engine and its per-call cost.

quote implements a string quoting function. The string will be wrapped in double quotes, and all valid CEL escape sequences will be escaped to show up

request constructs a `google.rpc.context.AttributeContext.Request` message.

sanitize replaces all invalid runes in the given string with utf8.RuneError.

subtractInt64Checked performs subtraction with overflow detection of two int64 values. If the operation fails the error return value will be non-nil.

trackListSelfCompare computes costs as a worst-case O(n^2) operation over the input list.

valSize returns the SizeEstimate for the value if one exists.

zeroValueOf will return the strongest possible proto.Message representing the default protobuf message value of the input msg type.

ActiveCalls returns the number of active asynchronous calls.

AddDeclFn declares a function in the environment but doesn't register an expr with it. This allows planning to succeed, but with no value for the func

AddDeclVar declares a variable in the environment but doesn't register an expr with it. This allows planning to succeed, but with no value for the var

AddFunctionDecls adds one or more functions to the config, converting them to serializable values first. FunctionDecl inputs are expected to be well-

AddMatch addes a Match to the rule.

AddOption adds an option to the basic environment. Options are applied before evaluating any of the let statements. Returns an error if setting the op

AddVariableDecls adds one or more variables to the config, converting them to serializable values first. VariableDecl inputs are expected to be well-

Append creates a new Errors object with the current and input errors.

Arg returns the ref.Val at the given index, or an error if one occurred.

AsCELFunction converts the serializable form of the Function into CEL environment declaration.

AsCELVariable converts the serializable form of the Variable into a CEL environment declaration.

ByteSource converts a byte sequence and location description to a model.Source.

Claim queries a claim value by key name using the provided types.Adapter, returning an optional dyn value.

ClearMacros options clears all parser macros. Clearing macros will ensure CEL expressions can only contain linear evaluation paths, as comprehensions

ClearOffsetRange removes the OffsetRange for the given expression id.

Clock sets a custom clock function for time validation (defaults to time.Now).

Cmd returns the normalized name for the command.

ComputeOffsetAbsolute calculates the 0-based character offset from a 1-based line and 0-based column based on the absolute line and column of the Sour

ConditionIsLiteral indicates whether the condition for the match is a literal with a given value.

ConfigFromYAML returns a config from YAML source. Adds custom parsing logic for normalizing shorthand for specifiying some fields in a YAML document

ConfigToYAML returns the config serialized to YAML Provided as a convenience wrapper around a tested YAML Marshaler.

Contains returns true if the input unknown is a subset of the current unknown.

ConvertToNative implements ref.Val.ConvertToNative.

ConvertToNative implements ref.Val.ConvertToNative.

ConvertToNative implements ref.Val.ConvertToNative.

ConvertToType implements ref.Val.ConvertToType.

ConvertToType implements ref.Val.ConvertToType.

ConvertToType implements ref.Val.ConvertToType.

Copy copies the current state of the registry into its own memory space.

CopySourceInfo creates a deep copy of the MacroCalls within the input SourceInfo. Copies of macro Expr values are generated using an internal default

CostObserver provides an observer that tracks runtime cost.

CostTrackerFactory configures the factory method to generate a new cost-tracker per-evaluation.

CostTrackerLimit sets the runtime limit on the evaluation cost during execution and will terminate the expression evaluation if the limit is exceeded.

CustomDecorator configures a custom interpretable decorator for the program.

DefaultTagVisitor creates a tag visitor which produces errors for any non-canonical YAML tag.

DefaultUTCTimeZone ensures that time-based operations use the UTC timezone rather than the input time's local timezone.

DelLetVar removes a variable from the evaluation context. If deleting the variable breaks a later expression, this function will return an error witho

Description provides an overview of the function's purpose. Usage examples should be included on specific overloads.

Description returns the usage documentation for the variable, if set. Good usage instructions provide information about the valid formats, ranges, si

DrainAll returns a strategy that waits for all currently pending calls to complete before re-evaluating. Note: This strategy is optimal for independe

DrainNone returns a strategy that re-evaluates after every single completion. This is the default strategy.

EnableCoverage returns a TestRunnerOption which enables coverage calculation for the test run.

EnableErrorOnBadPresenceTest error generation when a presence test or optional field selection is performed on a primitive type.

EnableErrorOnBadPresenceTest enables error generation when a presence test or optional field selection is performed on a primitive type.

EnableHiddenAccumulatorName uses an accumulator variable name that is not a normally accessible identifier in source for comprehension macros. Compati

EnableHiddenAccumulatorName sets the parser to use the identifier '@result' for accumulators which is not normally accessible from CEL source.
