Struct EnumPattern 

pub struct EnumPattern<'ast> {
    pub tag: LocIdent,
    pub pattern: Option<Pattern<'ast>>,
    pub pos: TermPos,
}

An enum pattern, including both an enum tag and an enum variant.

Fields

tag: LocIdent

pattern: Option<Pattern<'ast>>

pos: TermPos

Trait Implementations

impl<'ast> Clone for EnumPattern<'ast>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CloneTo for EnumPattern<'_>

type Data<'ast> = EnumPattern<'ast>

This is always Self, be we need associated types to make Rust understand that Self is always parametric over the 'ast lifetime. We’re using GATs to emulate higher-kinded types.

fn clone_to<'to>(data: Self::Data<'_>, dest: &'to AstAlloc) -> Self::Data<'to>

Clones owned data from the current allocator to dest.

impl<'ast> Debug for EnumPattern<'ast>

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

Formats the value using the given formatter.

impl Display for EnumPattern<'_>

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

Formats the value using the given formatter.

impl<'ast> FromAst<EnumPattern<'ast>> for PatternData

fn from_ast(enum_pat: &EnumPattern<'ast>) -> Self

impl<'ast> PartialEq for EnumPattern<'ast>

fn eq(&self, other: &EnumPattern<'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 &EnumPattern<'_>

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

Converts self into a document

impl Allocable for EnumPattern<'_>
