# Rusticata-macros
Helper macros for the [rusticata](https://github.com/rusticata) project.
This crate contains some additions to [nom](https://github.com/Geal/nom).
For example, the [`combinator::cond_else`] function allows to apply the first parser if the
condition is true, and the second if the condition is false:
```rust
use rusticata_macros::combinator::cond_else;
let r: IResult<_, _, ()> = cond_else(
|| s.len() > 1,
be_u16,
map(be_u8, u16::from)
)(s);
```
See the documentation for more details and examples.
