|
|
```
|
|
|
|
Decoding a `String`
|
|
```rust

## Installation
|
|
|
|
In order to use this crate, you have to add it under `[dependencies]` to your `Cargo.toml`

|
environment you can turn this off by adding the following
|
|
|
|
```toml
|
|
[dependencies]
|
|
hex = { version = "0.4", default-features = false }
|
|
```
|
|
|
|
