Crate rusticata_macros

Expand description

§Rusticata-macros

Helper macros for the rusticata project.

This crate contains some additions to 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:

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.
