Struct EnumValueDefinition 

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

An enum value definition within an enum type.

See Enum Value Definitions in the spec.

Unlike most other AST node types, this struct has no syntax field. The grammar (Description? EnumValue Directives[Const]?) contains no tokens beyond what the child nodes already capture: the name token is in Name’s syntax, directives in DirectiveAnnotation’s syntax, and description in StringValue’s syntax.

Fields

description: Option<StringValue<'src>>

directives: Vec<DirectiveAnnotation<'src>>

name: Name<'src>

span: ByteSpan

Implementations

impl<'src> EnumValueDefinition<'src>

pub fn name_value(&self) -> &str

Returns the name of this enum value definition as a string slice.

Convenience accessor for self.name.value.

impl EnumValueDefinition<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this enum value 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 enum value 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 EnumValueDefinition<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this enum value 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 enum value 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 EnumValueDefinition<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for EnumValueDefinition<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for EnumValueDefinition<'src>

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