Rust Match Pattern Cheatsheet

#rust #programming

Remembering all the various patterns that can be used in a match expression can be quite tricky, so here’s a free comprehensive list you can reference anytime 😄.

Pattern	Example
Wildcard	_
Literals	300 ”john”
Range	0 ..= 10 ’a’ ..= ‘z’
Variable	name mut name (Moves value into variable name)
ref Variable	ref name ref mut name
Reference	&value &(a, b) (Matches only reference values)
Tuple	(x, y, z)
Array	[r, g, b]
Slice	[a, b] [a, _, c] [a, .., z]
Enum	Some(value) None Day::Monday
Struct	Axis(x, y) Person {name, age} Profile {id, name, …} Shape {length: 10, active: true}
@ Binding	val @ 0 ..= 20 ref square @ Shape::Square {..}
Multiple patterns	‘a’ \ ‘b’
Guard expression	x if x*x <= 10
