Struct rune::ast::ExprLoop

pub struct ExprLoop {
    pub attributes: Vec<Attribute>,
    pub label: Option<(Label, Colon)>,
    pub loop_token: Loop,
    pub body: Box<Block>,
}

A loop expression: loop { ... }.

Examples

use rune::{testing, ast};

testing::roundtrip::<ast::ExprLoop>("loop {}");
testing::roundtrip::<ast::ExprLoop>("loop { 1; }");
testing::roundtrip::<ast::ExprLoop>("'label: loop {1;}");
testing::roundtrip::<ast::ExprLoop>("#[attr] 'label: loop {x();}");

Fields

attributes: Vec<Attribute>

The attributes for the loop

label: Option<(Label, Colon)>

A label followed by a colon.

loop_token: Loop

The loop keyword.

body: Box<Block>

The body of the loop.
