if_chain 0.1.3

Macro for writing nested `if let` expressions.


Build Status Cargo

This crate provides a single macro called if_chain!.

if_chain! lets you write long chains of nested if and if let statements without the associated rightward drift. It also supports multiple patterns (e.g. if let Foo(a) | Bar(a) = b) in places where Rust would normally not allow them.
