Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Template(TemplateDecl)

Template declaration.

Interface(InterfaceDecl)

Interface declaration.

Function(FunctionDecl)

Function signature/equations grouped by name.

TypeDef

data/type/class/instance/exception — recorded with name + span.

Fields

keyword: String

Declaration keyword (data, type, class, …).

name: Identifier

Declared type/class/instance name as parsed.

pos: Pos

Position of the declaration keyword.

span: Span

Span of the declaration header/body consumed by the parser.

Fixity(FixityDecl)

Top-level fixity declaration.

UnsupportedSyntax

Top-level syntax the parser recognizes but intentionally does not model.

Fields

kind: UnsupportedSyntaxKind

Why the declaration is unsupported.

raw: String

Raw source text of the declaration.

pos: Pos

Position of the declaration’s first token.

span: Span

Span of the declaration text.

Unknown

Anything unparseable at the top level (diagnostic already emitted).

Fields

raw: String

Raw source text of the skipped declaration.

pos: Pos

Position of the skipped declaration’s first token.

span: Span

Span of the skipped declaration text.

Trait Implementations

impl Clone for Decl

fn clone(&self) -> Decl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Decl

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

Formats the value using the given formatter.

impl Eq for Decl

impl PartialEq for Decl

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