import "github.com/zeebo/rothko/internal/typeassert"
package typeassert provides helper functions type asserting structures.
Usage
type Asserter
type Asserter struct {
}
Asserter helps type assertions with an "all-or-nothing" style API.
func A
func A(x interface{}) *Asserter
A wraps the value in an Asserter.
func (*Asserter) Bool
func (a *Asserter) Bool() bool
Bool asserts the value as a bool.
func (*Asserter) Err
func (a *Asserter) Err() error
Err returns an error if any of the assertions failed. If the error is not nil, none of the assertions are valid.
func (*Asserter) Float64
func (a *Asserter) Float64() float64
Float64 asserts the value as a float64.
func (*Asserter) I
func (a *Asserter) I(index string) *Asserter
I indexes into a map[string]interface{}.
func (*Asserter) Int
func (a *Asserter) Int() int
Int asserts the value as an int.
func (*Asserter) Int64
func (a *Asserter) Int64() int64
Int64 asserts the value as an int64.
func (*Asserter) N
func (a *Asserter) N(index int) *Asserter
N indexes into a []interface{}.
func (*Asserter) String
func (a *Asserter) String() string
String asserts the value as a string.
func (*Asserter) V
func (a *Asserter) V() interface{}
V returns the current value pointed at by the Asserter.
