[−][src]Macro conditional::conditional
Lets you use the syntax of the conditional operator in Rust. Also known as the ternary operator.
Examples
let x = conditional!(69 > 42 ? "hello" : "world"); assert_eq!(x, "hello");
let r: Result<i32, String> = Ok(5); // More complicated expressions are supported, but you might have to use // parentheses to satisfy the macro parser let x = conditional!((r? > 42) ? "hello" : "world"); assert_eq!(x, "world");
// More complicated expressions are supported, but you might have to use // parentheses to satisfy the macro parser let x = conditional!(("3".parse::<i32>().map_err(|e| e.to_string())? > 42) ? "hello" : "world"); assert_eq!(x, "world");
