Function string

cel/src/functions.rs:143–156

Performs a type conversion on the target. The following conversions are currently supported: `string` - Returns a copy of the target string. `timestamp` - Returns the timestamp in RFC3339 format. `duration` - Returns the duration in a string formatted like "72h3m0.5s". `int` - Returns the integer value of the target. `uint` - Returns the unsigned integer value of the target. `float` - Returns the

(ftx: &FunctionContext, This(this): This<Value>)

// * `float` - Returns the float value of the target.
// * `bytes` - Converts bytes to string using from_utf8_lossy.
