Struct Arg

stack/stack.go:114–144

Arg is an argument on a Call.

// Arg is an argument on a Call.
type Arg struct {
	// IsAggregate is true if the argument is an aggregate type. If true, the
	// argument does not contain a value itself, but contains a set of nested
	// argument fields. If false, the argument contains a single scalar value.
	IsAggregate bool

	// The following are set if IsAggregate == false.

	// Name is a pseudo name given to the argument.
	Name string
	// Value is the raw value as found in the stack trace
	Value uint64
	// IsPtr is true if we guess it's a pointer. It's only a guess, it can be
	// easily confused by a bitmask.
	IsPtr bool
	// IsOffsetTooLarge is true if the argument's frame offset was too large,
	// preventing the argument from being printed in the stack trace.
	IsOffsetTooLarge bool

	// IsInaccurate determines if Value is inaccurate. Stacks could have inaccurate values
	// for arguments passed in registers. Go 1.18 prints a ? for these values.
	IsInaccurate bool

	// The following are set if IsAggregate == true.

	// Fields are the fields/elements of aggregate-typed arguments.
	Fields Args

	// Disallow initialization with unnamed parameters.
