Struct rune::ast::ExprUnary

pub struct ExprUnary {
    pub attributes: Vec<Attribute>,
    pub op_token: Token,
    pub expr: Expr,
    pub op: UnOp,
}

A unary expression.

Examples

use rune::{testing, ast};

testing::roundtrip::<ast::ExprUnary>("!0");
testing::roundtrip::<ast::ExprUnary>("*foo");
testing::roundtrip::<ast::ExprUnary>("&foo");
testing::roundtrip::<ast::ExprUnary>("&Foo {
    a: 42,
}");

Fields

attributes: Vec<Attribute>

Attributes associated with expression.

op_token: Token

Token associated with operator.

expr: Expr

The expression of the operation.

op: UnOp

The operation to apply.
