Functions ¶
func BaseTypeOf ¶
func BaseValueOf ¶
func Equal ¶
Equal will compare two value deeply. It looks for Equal method on the value as well. You can define how a type's value should be compared by using RegisterEqual.
Example ¶
package main
import (
"go.llib.dev/frameless/pkg/reflectkit"
)
func main() {
reflectkit.Equal("a", "a") // true
reflectkit.Equal("a", "b") // false
}
func FullyQualifiedName ¶
Example ¶
package main
import (
"fmt"
"go.llib.dev/frameless/pkg/reflectkit"
)
func main() {
fmt.Println(reflectkit.FullyQualifiedName(Example{}))
}
type Example struct {
Name string
}
func IsMutableType ¶ added in v0.280.0
func Link ¶
Link will make destination interface be linked with the src value.
Example ¶
package main
import (
"go.llib.dev/frameless/pkg/reflectkit"
)
func main() {
var src = Example{Name: "Panda"}
var dest Example
if err := reflectkit.Link(src, &dest); err != nil {
// handle err
}
}
type Example struct {
Name string
}
func LookupField ¶ added in v0.278.0
func LookupField[FieldID LookupFieldID](rStruct reflect.Value, i FieldID) (reflect.StructField, reflect.Value, bool)
func OverStructFields ¶ added in v0.280.0
func RegisterEqual ¶
func SymbolicName ¶
Example ¶
package main
import (
"fmt"
"go.llib.dev/frameless/pkg/reflectkit"
)
func main() {
fmt.Println(reflectkit.SymbolicName(Example{}))
}
type Example struct {
Name string
}
func ToSettable ¶ added in v0.278.0
Example ¶
package main
import (
"reflect"
"go.llib.dev/frameless/pkg/reflectkit"
)
func main() {
type T struct{ v int }
var v T
_ = v.v
ptr := reflect.ValueOf(&v)
rStruct := ptr.Elem()
got, ok := reflectkit.ToSettable(rStruct.FieldByName("v"))
_, _ = got, ok
}
Types ¶
type LookupFieldID ¶ added in v0.280.0
type LookupFieldID interface {
reflect.StructField | int | string
}
type TagHandler ¶ added in v0.280.0
type TagHandler[T any] struct { Name string Parse func(sf reflect.StructField, tagValue string) (T, error) Use func(sf reflect.StructField, field reflect.Value, v T) error // ForceCache will force the TagHandler to cache the parse results, regardless if the value is mutable or not. ForceCache bool // HandleUntagged will force the Handle functions to call Parse and Use even on fields where tag is empty. HandleUntagged bool // contains filtered or unexported fields }
func (*TagHandler[T]) HandleStruct ¶ added in v0.280.0
func (h *TagHandler[T]) HandleStruct(rStruct reflect.Value) error
func (*TagHandler[T]) HandleStructField ¶ added in v0.280.0
func (h *TagHandler[T]) HandleStructField(field reflect.StructField, value reflect.Value) error
func (*TagHandler[T]) LookupTag ¶ added in v0.280.0
func (h *TagHandler[T]) LookupTag(field reflect.StructField) (T, bool, error)
