[−][src]Crate postfix_macros

Postfix macros on stable Rust, today.

postfix_macros! {
	"hello world".println!();
	42.assert_ne!(4 + 2);

	val.iter()
		.map(|v| v.1)
		.find(|z| z.matches!(Custom::Enum(_) | Custom::EnumOther))
		.dbg!()
		.unwrap_or!{ return };
}

The crate provides the postfix_macros! macro, as well as some helpful macros for use in a postfix context, for your greatest convenience.

Rust construct	postfix replacement macro
`unwrap_or`, `unwrap_or_else`	`unwrap_or!`
`if let` with else clause	`match_or!`
`match` with default case	`match_or!`
`if` `<bool>`, `bool::then`	`then!`
`else`	`then_else!`

Macros

match_or	`match` macro with a default case shorthand
postfix_macros	Proc macro to parse code containing postfix macros, to rewrite it to use traditional macro invocations.
then	Executes the body if the argument is `true`
then_else	`else` clauses for the `then!` macro
unwrap_or	Either unwraps the content passed to the macro, or executes the passed code block.
