coerce_pattern

coerce_pattern is a Rust library crate containing macros that force expressions into patterns. It is version-controlled on GitHub here.

This crate contains two proc macros relating to asserting, under penalty of panic, that expressions match patterns.

1. coerce_pattern! matches an expression to a target pattern and evaluates to an expression of the inner variables from the pattern, panicking if the pattern doesn't match
2. assert_pattern! matches an expression to a target and panics if the pattern doesn't match.

To use them, run the following command in your project directory.

cargo add coerce_pattern

Then, you can use the macros using

use coerce_pattern::{coerce_pattern, assert_pattern};
