Struct ScalarTypeDefinition 

pub struct ScalarTypeDefinition<'src> {
    pub description: Option<StringValue<'src>>,
    pub directives: Vec<DirectiveAnnotation<'src>>,
    pub name: Name<'src>,
    pub span: ByteSpan,
    pub syntax: Option<Box<ScalarTypeDefinitionSyntax<'src>>>,
}

A scalar type definition (e.g. scalar DateTime).

See Scalars in the spec.

Fields

description: Option<StringValue<'src>>

directives: Vec<DirectiveAnnotation<'src>>

name: Name<'src>

span: ByteSpan

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

Implementations

impl<'src> ScalarTypeDefinition<'src>

pub fn name_value(&self) -> &str

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

Convenience accessor for self.name.value.

impl ScalarTypeDefinition<'_>

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 definition’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 definition’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 ScalarTypeDefinition<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this scalar type definition’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 definition’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 ScalarTypeDefinition<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for ScalarTypeDefinition<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for ScalarTypeDefinition<'src>

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