TestSetter_CalledOnPointerToNonStruct pins the setter calls a non-struct type gets: one behind a pointer the tag allocated, unless its unmarshaler too

TestSetter_CalledOnValueReceiver pins that a setter declared on a value receiver is called. The pointer's method set lists it as a wrapper the compile

TestSetter_EmbeddedPointerStruct pins that a struct's own setter and an embedded one both run. setterOuter declares a SetDefaults, which hides SetterI

TestSetter_NotCalledThroughEmbeddedInterface pins that an embedded interface gets no setter, the same as a named one. Go promotes the interface's SetD

TestUnmarshalTag_TextIsAskedFirst covers the order: a target that implements both is asked through UnmarshalText, and UnmarshalJSON is never offered t

TestWalking_KeyNamesTheValueItsTypeAndItsLength covers what an entry is to the index: two entries have one key only if they name the same value, under

TestWalking_LeaveTakesOnlyItsOwnEntryOut covers what leave does as a walk returns, called as it is on every return, including one the index never held

TestWalking_RepeatsFarIndexesThePathAboveIt covers the first check below scanDepth: it makes the index, gives it to every entry on the path, and adds

TestWalking_RepeatsNearFindsTheSameValueAbove covers the scan, which a value no more than scanDepth down is checked by: the whole path above it, for a

TestWalking_RepeatsNearLeavesDeeperValuesToRepeatsFar covers the split between the two: the scan gives up below scanDepth, where it would cost more th

benchFail measures a Set on a zero T that fails. valid checks the first error.
