vendor: github.com/compose-spec/compose-go/v2 v2.1.2

Replaces uses of the github.com/mitchellh/mapstructure module, which
was deprecated by the owner and moved to new maintainership at
github.com/go-viper/mapstructure.

The old module is still referenced as indirect dependency (through
docker/cli and theupdateframework/notary), but not used in code, and
should eventually go away.

## 1.5.0
* New option `IgnoreUntaggedFields` to ignore decoding to any fields
without `mapstructure` (or the configured tag name) set [GH-277]
* New option `ErrorUnset` which makes it an error if any fields
in a target struct are not set by the decoding process. [GH-225]
* New function `OrComposeDecodeHookFunc` to help compose decode hooks. [GH-240]
* Decoding to slice from array no longer crashes [GH-265]
* Decode nested struct pointers to map [GH-271]
* Fix issue where `,squash` was ignored if `Squash` option was set. [GH-280]

into a map with an empty string key [GH-281]
## 1.4.3
* Fix cases where `json.Number` didn't decode properly [GH-261]

field names. [GH-250]

## 1.4.1
* Fix regression where `*time.Time` value would be set to empty and not be sent
to decode hooks properly [GH-232]
## 1.4.0

access to the full values. [GH-183]
* Squash is now supported with embedded fields that are struct pointers [GH-205]

* Decode into interface type with a struct value is supported [GH-187]
## 1.3.1
* Squash should only squash embedded structs. [GH-194]

or "remain" value. [GH-150]
## 1.2.1
* Go modules checksum mismatch fix
## 1.2.0
* Added support to capture unused values in a field using the `",remain"` value
in the mapstructure tag. There is an example to showcase usage.

* Support struct to struct decoding [GH-137]
* If source map value is nil, then destination map value is nil (instead of empty)
* If source slice value is nil, then destination slice value is nil (instead of empty)
* If source pointer is nil, then destination pointer is set to nil (instead of
allocated zero value of type)

# mapstructure [![Godoc](https://godoc.org/github.com/mitchellh/mapstructure?status.svg)](https://godoc.org/github.com/mitchellh/mapstructure)
mapstructure is a Go library for decoding generic map values to structures
and vice versa, while providing helpful error handling.
This library is most useful when decoding values from some data stream (JSON,
Gob, etc.) where you don't _quite_ know the structure of the underlying data
until you read a part of it. You can therefore read a `map[string]interface{}`
and use this library to decode it into the proper underlying native Go
structure.
## Installation
Standard `go get`:
```
$ go get github.com/mitchellh/mapstructure
```
## Usage & Example
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
The `Decode` function has examples associated with it there.
## But Why?!
Go offers fantastic standard libraries for decoding formats such as JSON.
The standard method is to have a struct pre-created, and populate that struct
from the bytes of the encoded format. This is great, but the problem is if
you have configuration or an encoding that changes slightly depending on
specific fields. For example, consider this JSON:
```json
{
"type": "person",
"name": "Mitchell"
}
```
Perhaps we can't populate a specific structure without first reading
the "type" field from the JSON. We could always do two passes over the
decoding of the JSON (reading the "type" first, and the rest later).
However, it is much simpler to just decode this into a `map[string]interface{}`
structure, read the "type" key, then use something like this library
to decode it into the proper structure.
