Enum xlang_syntax::ast::MapPair

pub enum MapPair<'input> {
    Local {
        loc: Loc,
        name: Ident<'input>,
    },
    Literal {
        loc: Loc,

    Evaluated {

    },
}

A key and value in a map literal.

Variants

Local

Fields

loc: Loc

name: Ident<'input>

A local variable will be used as the value.

Literal

Fields

loc: Loc

name: Ident<'input>

value: Box<Expr<'input>>

A value has been explicitly used as the name.

Evaluated

Fields

loc: Loc

name: Box<Expr<'input>>

value: Box<Expr<'input>>

An expression is used as the key and will be evaluated at runtime.

Implementations

impl<'input> MapPair<'input>

pub fn local(loc: Loc, name: Ident<'input>) -> Self

Creates a local map pair.

pub fn literal(loc: Loc, name: Ident<'input>, value: Box<Expr<'input>>) -> Self

Creates a literal map pair.

pub fn evaluated(
    loc: Loc,
    name: Box<Expr<'input>>,
    value: Box<Expr<'input>>
) -> Self

Creates a expre map pair.

Trait Implementations

impl<'input> Clone for MapPair<'input>

fn clone(&self) -> MapPair<'input>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'input> Debug for MapPair<'input>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'input> Locate for MapPair<'input>

fn loc(&self) -> Loc

Returns the location of this expression.

impl<'input> PartialEq<MapPair<'input>> for MapPair<'input>

fn eq(&self, other: &MapPair<'input>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
