+ +This library provides options for fast detection and rejection of duplicate map keys based on applying a Go-specific data model to CBOR's extended generic data model in order to determine duplicate vs distinct map keys. Detection relies on whether the CBOR map key would be a duplicate "key" when decoded and applied to the user-provided Go map or struct. + +`DupMapKeyQuiet` turns off detection of duplicate map keys. It tries to use a "keep fastest" method by choosing either "keep first" or "keep last" depending on the Go data type. + +`DupMapKeyEnforcedAPF` enforces detection and rejection of duplidate map keys. Decoding stops immediately and returns `DupMapKeyError` when the first duplicate key is detected. The error includes the duplicate map key and the index number. + +APF suffix means "Allow Partial Fill" so the destination map or struct can contain some decoded values at the time of error. It is the caller's responsibility to respond to the `DupMapKeyError` by discarding the partially filled result if that's required by their protocol. + +
+ +This library checks tag validity for built-in tags (currently tag numbers 0, 1, 2, 3, and 55799): + +* Inadmissible type for tag content +* Inadmissible value for tag content + +Unknown tag data items (not tag number 0, 1, 2, 3, or 55799) are handled in two ways: + +* When decoding into an empty interface, unknown tag data item will be decoded into `cbor.Tag` data type, which contains tag number and tag content. The tag content will be decoded into the default Go data type for the CBOR data type. +* When decoding into other Go types, unknown tag data item is decoded into the specified Go type. If Go type is registered with a tag number, the tag number can optionally be verified. + +Decoder also has an option to forbid tag data items (treat any tag data item as error) which is specified by protocols such as CTAP2 Canonical CBOR. + +For more information, see [decoding options](#decoding-options-1) and [tag options](#tag-options). + +

-## Install
-
- go get github.com/imdario/mergo
-
- // use in your .go code
- import (
- "github.com/imdario/mergo"
- )
-
-## Usage
-
-You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are zero values](https://golang.org/ref/spec#The_zero_value) too. Also, maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
-
-```go
-if err := mergo.Merge(&dst, src); err != nil {
- // ...
-}
-```
-
-Also, you can merge overwriting values using the transformer `WithOverride`.
-
-```go
-if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
- // ...
-}
-```
-
-Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
-
-```go
-if err := mergo.Map(&dst, srcMap); err != nil {
- // ...
-}
-```
-
-Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
-
-Here is a nice example:
-
-```go
-package main
-
-import (
- "fmt"
- "github.com/imdario/mergo"
-)
-
-type Foo struct {
- A string
- B int64
-}
-
-func main() {
- src := Foo{
- A: "one",
- B: 2,
- }
- dest := Foo{
- A: "two",
- }
- mergo.Merge(&dest, src)
- fmt.Println(dest)
- // Will print
- // {two 2}
-}
-```
-
-Note: if test are failing due missing package, please execute:
-
- go get gopkg.in/yaml.v3
-
-### Transformers
-
-Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
-
-```go
-package main
-
-import (
- "fmt"
- "github.com/imdario/mergo"
- "reflect"
- "time"
-)
-
-type timeTransformer struct {
-}
-
-func (t timeTransformer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
- if typ == reflect.TypeOf(time.Time{}) {
- return func(dst, src reflect.Value) error {
- if dst.CanSet() {
- isZero := dst.MethodByName("IsZero")
- result := isZero.Call([]reflect.Value{})
- if result[0].Bool() {
- dst.Set(src)
- }
- }
- return nil
- }
- }
- return nil
-}
-
-type Snapshot struct {
- Time time.Time
- // ...
-}
-
-func main() {
- src := Snapshot{time.Now()}
- dest := Snapshot{}
- mergo.Merge(&dest, src, mergo.WithTransformers(timeTransformer{}))
- fmt.Println(dest)
- // Will print
- // { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
-}

-A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
-
-Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
-
-Status
-
-It is ready for production use. It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc.
-
-Important note
-
-Please keep in mind that a problematic PR broke 0.3.9. We reverted it in 0.3.10. We consider 0.3.10 as stable but not bug-free. . Also, this version adds suppot for go modules.
-
-Keep in mind that in 0.3.2, Mergo changed Merge() and Map() signatures to support transformers. We added an optional/variadic argument so that it won't break the existing code.
-
-If you were using Mergo before April 6th, 2015, please check your project works as intended after updating your local copy with go get -u github.com/imdario/mergo. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause in existing projects after the change (release 0.2.0).
-
-Install
