Enum muse_lang::compiler::syntax::EntryKeyPattern

pub enum EntryKeyPattern {
    Nil,
    Bool(bool),
    Int(i64),
    UInt(u64),
    Float(f64),
    String(Symbol),
    Identifier(Symbol),
}

The syntax components of the key portion of a pattern match on a map field.

Variants

Nil

Match if nil

Bool(bool)

Match if a boolean of a given value.

Int(i64)

Match if an integer of a given value.

While this pattern is unsigned, if an unsigned integer has the same numerical value, it will still match.

UInt(u64)

Match if an integer of a given value.

While this pattern is unsigned, if a signed integer has the same numerical value, it will still match.

Float(f64)

Match if a float of a given value.

Float matching checks if the difference between the pattern and value is less than f64::EPSILON.

String(Symbol)

Match if a string of a given value.

Identifier(Symbol)

Match against a value contained in a variable.

Trait Implementations

impl Clone for EntryKeyPattern

fn clone(&self) -> EntryKeyPattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EntryKeyPattern

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

Formats the value using the given formatter.

impl PartialEq for EntryKeyPattern

fn eq(&self, other: &EntryKeyPattern) -> 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.
