serde_urlencoded_field

文档

lib.rs:

This is a helper module for using serde_drive. It allows you to specify that
some fields in your type will be automatically percent-encoded on
serialization and percent-decoded on deserialization.

## Example

```
use serde_derive::{Deserialize, Serialize};

#[derive(Debug, Deserialize, Serialize, PartialEq)]
struct Item {
	#[serde(with="serde_urlencoded_field::path_segment")]
	id: String,
	mime: String,
}

let item = Item {
	id: "my/item".to_string(),
	mime: "application/wasm".to_string(),
};

let json = serde_json::to_string(&item).unwrap();
assert_eq!(json, r#"{"id":"my%2Fitem","mime":"application/wasm"}"#);

let item2: Item = serde_json::from_str(&json).unwrap();
assert_eq!(item2, item);
```

## Types

serde_urlencoded_field can serialize anything that implements `AsRef<[u8]>`,
including `String`, `&str`, `Vec<u8>` and `&[u8]`.

serde_urlencoded_field can deserialize into `String` and `Vec<u8>`. Other
types can be added by implementing the FromPercentDecode trait.
