Struct rune::ast::ExprYield

pub struct ExprYield {
    pub attributes: Vec<Attribute>,
    pub yield_token: Yield,
    pub expr: Option<Expr>,
}

A yield [expr] expression to return a value from a generator.

Examples

use rune::{testing, ast};

testing::roundtrip::<ast::ExprYield>("yield");
testing::roundtrip::<ast::ExprYield>("yield 42");
testing::roundtrip::<ast::ExprYield>("#[attr] yield 42");

Fields

attributes: Vec<Attribute>

The attributes of the yield

yield_token: Yield

The return token.

expr: Option<Expr>

An optional expression to yield.
