Struct NamedTypeAnnotation 

pub struct NamedTypeAnnotation<'src> {
    pub name: Name<'src>,
    pub nullability: Nullability<'src>,
    pub span: ByteSpan,
}

A named type reference (e.g. String, String!).

See Type References in the spec. The span covers the full annotation including ! when present. The underlying name span is available via name.span.

Unlike most other AST node types, this struct has no syntax field. The grammar contains no tokens beyond what the child nodes already capture: the name token is in Name’s syntax and the ! token (if present) is in Nullability::NonNull’s syntax.

Fields

name: Name<'src>

nullability: Nullability<'src>

span: ByteSpan

Implementations

impl<'src> NamedTypeAnnotation<'src>

pub fn nullable(&self) -> bool

Returns true if this type annotation is nullable (i.e. does not have a trailing !).

pub fn name_value(&self) -> &str

Returns the name of this type annotation as a string slice.

Convenience accessor for self.name.value.

impl NamedTypeAnnotation<'_>

pub fn append_source(&self, sink: &mut String, source: Option<&str>)

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this type annotation’s byte-offset span within the source text.

The returned ByteSpan can be resolved to line/column positions via source_span() or ByteSpan::resolve().

pub fn source_span(&self, source_map: &SourceMap<'_>) -> Option<SourceSpan>

Resolves this type annotation’s position to line/column coordinates using the given SourceMap.

Returns None if the byte offsets cannot be resolved (e.g. the span was synthetically constructed without valid position data).

Trait Implementations

impl AstNode for NamedTypeAnnotation<'_>

fn append_source(&self, sink: &mut String, source: Option<&str>)

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this type annotation’s byte-offset span within the source text.

The returned ByteSpan can be resolved to line/column positions via source_span() or ByteSpan::resolve().

fn source_span(&self, source_map: &SourceMap<'_>) -> Option<SourceSpan>

Resolves this type annotation’s position to line/column coordinates using the given SourceMap.

Returns None if the byte offsets cannot be resolved (e.g. the span was synthetically constructed without valid position data).

fn to_source(&self, source: Option<&str>) -> String

Return this node as a source string.

impl<'src> Clone for NamedTypeAnnotation<'src>

fn clone(&self) -> NamedTypeAnnotation<'src>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for NamedTypeAnnotation<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for NamedTypeAnnotation<'src>

fn eq(&self, other: &NamedTypeAnnotation<'src>) -> 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.
