Types

type Converter

type Converter interface {
	// Bool returns the bool representation from the given interface value.
	// Returns the default value of false and an error on failure.
	Bool(from interface{}) (to bool, err error)

	// Duration returns the time.Duration representation from the given
	// interface{} value. Returns the default value of 0 and an error on failure.
	Duration(from interface{}) (to time.Duration, err error)

	// Float32 returns the float32 representation from the given empty interface
	// value. Returns the default value of 0 and an error on failure.
	Float32(from interface{}) (to float32, err error)

	// Float64 returns the float64 representation from the given interface
	// value. Returns the default value of 0 and an error on failure.
	Float64(from interface{}) (to float64, err error)

	// Infer will perform conversion by inferring the conversion operation from
	// a pointer to a supported T of the `into` param.
	Infer(into, from interface{}) error

	// Int returns the int representation from the given empty interface
	// value. Returns the default value of 0 and an error on failure.

	// value. Returns the default value of 0 and an error on failure.

	// value and can not fail. An error is provided only for API cohesion.
