Struct muse_lang::compiler::syntax::PatternComparison

pub struct PatternComparison {
    pub kind: Ranged<CompareKind>,
    pub expr: Box<Ranged<Expression>>,
}

A comparision pattern for comparing against a non-literal value.

Literal values are unambiguous, but named values like enums lead to ambiguity as to whether the programmer wants a new variable with a given name or if it should be matched against.

Fields

kind: Ranged<CompareKind>

The kind of comparison to perform.

expr: Box<Ranged<Expression>>

The expression to evaluate to compare against.

Trait Implementations

impl Clone for PatternComparison

fn clone(&self) -> PatternComparison

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PatternComparison

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

Formats the value using the given formatter.

impl PartialEq for PatternComparison

fn eq(&self, other: &PatternComparison) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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