Struct rune::ast::Local

pub struct Local {
    pub attributes: Vec<Attribute>,
    pub let_token: Let,
    pub pat: Pat,
    pub eq: Eq,
    pub expr: Expr,
    pub semi: SemiColon,
}

A local variable declaration let <pattern> = <expr>;

Examples

use rune::{testing, ast};

testing::roundtrip::<ast::Local>("let x = 1;");
testing::roundtrip::<ast::Local>("#[attr] let a = f();");
testing::roundtrip::<ast::Local>("let a = b{}().foo[0].await;");

Fields

attributes: Vec<Attribute>

The attributes for the let expression

let_token: Let

The let keyword.

pat: Pat

The name of the binding.

eq: Eq

The equality keyword.

expr: Expr

The expression the binding is assigned to.

semi: SemiColon
