Struct ScalarTypeExtension 

pub struct ScalarTypeExtension<'src> {
    pub directives: Vec<DirectiveAnnotation<'src>>,
    pub name: Name<'src>,
    pub span: ByteSpan,
    pub syntax: Option<Box<ScalarTypeExtensionSyntax<'src>>>,
}

A scalar type extension.

See Scalar Extensions in the spec.

Spec invariant

The spec grammar requires at least one directive. For a spec-valid node, directives is always non-empty.

Fields

directives: Vec<DirectiveAnnotation<'src>>

name: Name<'src>

span: ByteSpan

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

Implementations

impl<'src> ScalarTypeExtension<'src>

pub fn name_value(&self) -> &str

Returns the name of this scalar type extension as a string slice.

Convenience accessor for self.name.value.

impl ScalarTypeExtension<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this scalar type extension’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 scalar type extension’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 ScalarTypeExtension<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this scalar type extension’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 scalar type extension’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 ScalarTypeExtension<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for ScalarTypeExtension<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for ScalarTypeExtension<'src>

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