This crate contains two proc macros relating to asserting, under penalty of panic, that expressions match patterns.
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 matchassert_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};
See below for detailed documentation on the macros.
