Struct ListTypeAnnotation 

pub struct ListTypeAnnotation<'src> {
    pub element_type: Box<TypeAnnotation<'src>>,
    pub nullability: Nullability<'src>,
    pub span: ByteSpan,
    pub syntax: Option<Box<ListTypeAnnotationSyntax<'src>>>,
}

A list type reference (e.g. [String], [String!]!).

See Type References in the spec. The span covers brackets and trailing ! when present.

Fields

element_type: Box<TypeAnnotation<'src>>

nullability: Nullability<'src>

span: ByteSpan

syntax: Option<Box<ListTypeAnnotationSyntax<'src>>>

Implementations

impl<'src> ListTypeAnnotation<'src>

pub fn nullable(&self) -> bool

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

impl ListTypeAnnotation<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this list 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 list 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 ListTypeAnnotation<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this list 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 list 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 ListTypeAnnotation<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for ListTypeAnnotation<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for ListTypeAnnotation<'src>

fn eq(&self, other: &ListTypeAnnotation<'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.
