Functions ¶

func AsTime ¶

func AsTime(v reflect.Value, loc *time.Location) (time.Time, bool)

AsTime returns v as a time.Time if possible. The given location is only used if the value implements AsTimeProvider (e.g. go-toml local). A zero Time and false is returned if this isn't possible. Note that this function does not accept string dates.

func CallMethodByName ¶

func CallMethodByName(cxt context.Context, name string, v reflect.Value) []reflect.Value

func GetMethodByName ¶

func GetMethodByName(v reflect.Value, name string) reflect.Value

GetMethodByName is the same as reflect.Value.MethodByName, but it caches the type lookup.

func GetMethodIndexByName ¶

func GetMethodIndexByName(tp reflect.Type, name string) int

GetMethodIndexByName returns the index of the method with the given name, or -1 if no such method exists.

func IsContextType ¶

func IsContextType(tp reflect.Type) bool

IsContextType returns whether tp is a context.Context type.

func IsFloat ¶

func IsFloat(kind reflect.Kind) bool

IsFloat returns whether the given kind is a float.

func IsInt ¶

func IsInt(kind reflect.Kind) bool

IsInt returns whether the given kind is an int.

func IsMap ¶

func IsMap(v any) bool

IsMap reports whether v is a map.

func IsNumber ¶

func IsNumber(kind reflect.Kind) bool

TODO(bep) replace the private versions in /tpl with these. IsNumber returns whether the given kind is a number.

func IsSlice ¶

func IsSlice(v any) bool

IsSlice reports whether v is a slice.

func IsTime ¶

func IsTime(tp reflect.Type) bool

IsTime returns whether tp is a time.Time type or if it can be converted into one in ToTime.

func IsTruthful ¶

func IsTruthful(in any) bool

IsTruthful returns whether in represents a truthful value. See IsTruthfulValue

func IsTruthfulValue ¶

func IsTruthfulValue(val reflect.Value) (truth bool)

IsTruthfulValue returns whether the given value has a meaningful truth value. This is based on template.IsTrue in Go's stdlib, but also considers IsZero and any interface value will be unwrapped before it's considered for truthfulness.

Based on: https://github.com/golang/go/blob/178a2c42254166cffed1b25fb1d3c7a5727cada6/src/text/template/exec.go#L306

func IsUint ¶

func IsUint(kind reflect.Kind) bool

IsUint returns whether the given kind is an uint.

func IsValid ¶

func IsValid(v reflect.Value) bool

IsValid returns whether v is not nil and a valid value.

func ToSliceAny ¶

func ToSliceAny(v any) ([]any, bool)

ToSliceAny converts the given value to a slice of any if possible.
