Enum PatternData 

pub enum PatternData<'ast> {
    Wildcard,
    Any(LocIdent),
    Record(&'ast RecordPattern<'ast>),

Variants

Wildcard

A wildcard pattern, matching any value. As opposed to any, this pattern doesn’t bind any variable.

Any(LocIdent)

A simple pattern consisting of an identifier. Match anything and bind the result to the corresponding identifier.

Record(&'ast RecordPattern<'ast>)

A record pattern as in { a = { b, c } }

Array(&'ast ArrayPattern<'ast>)

An array pattern as in [a, b, c]

Enum(&'ast EnumPattern<'ast>)

An enum pattern as in 'Foo x or 'Foo

Constant(&'ast ConstantPattern<'ast>)

A constant pattern as in 42 or true.

Or(&'ast OrPattern<'ast>)

A sequence of alternative patterns as in 'Foo _ or 'Bar _ or 'Baz _.

Trait Implementations

impl<'ast> Clone for PatternData<'ast>

fn clone(&self) -> PatternData<'ast>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'ast> Debug for PatternData<'ast>

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

Formats the value using the given formatter.

impl Display for PatternData<'_>

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

Formats the value using the given formatter.

impl<'ast> PartialEq for PatternData<'ast>

fn eq(&self, other: &PatternData<'ast>) -> 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.

impl<'a> Pretty<'a, Allocator> for &PatternData<'_>

fn pretty(self, allocator: &'a Allocator) -> DocBuilder<'a, Allocator>

Converts self into a document
