[Documentation](https://docs.rs/bytes)
## Usage
To use `bytes`, first add this to your `Cargo.toml`:
```toml
[dependencies]
bytes = "1"
```
Next, add this to your crate:
```rust
use bytes::{Bytes, BytesMut, Buf, BufMut};
```
## no_std support
To use `bytes` with no_std environment, disable the (enabled by default) `std` feature.
```toml
[dependencies]
bytes = { version = "1", default-features = false }
```
To use `bytes` with no_std environment without atomic CAS, such as thumbv6m, you also need to enable
the `extra-platforms` feature. See the [documentation for the `portable-atomic`
crate](https://docs.rs/portable-atomic) for more information.
The MSRV when `extra-platforms` feature is enabled depends on the MSRV of `portable-atomic`.
## Serde support
Serde support is optional and disabled by default. To enable use the feature `serde`.
```toml
[dependencies]
bytes = { version = "1", features = ["serde"] }
```
The MSRV when `serde` feature is enabled depends on the MSRV of `serde`.
## Building documentation
When building the `bytes` documentation the `docsrs` option should be used, otherwise
feature gates will not be shown. This requires a nightly toolchain:
```
RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc
```
## License
This project is licensed under the [MIT license](LICENSE).
### Contribution
Unless you explicitly state otherwise, any contribution intentionally submitted
for inclusion in `bytes` by you, shall be licensed as MIT, without any additional
terms or conditions.
