Struct DirectiveAnnotation 

pub struct DirectiveAnnotation<'src> {
    pub arguments: Vec<Argument<'src>>,
    pub name: Name<'src>,
    pub span: ByteSpan,
    pub syntax: Option<Box<DirectiveAnnotationSyntax<'src>>>,
}

A directive annotation applied to a definition or field (e.g. @deprecated(reason: "Use newField")).

See Directives in the spec. Note: this represents an applied directive (an annotation), not a directive definition.

Fields

arguments: Vec<Argument<'src>>

name: Name<'src>

span: ByteSpan

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

Implementations

impl<'src> DirectiveAnnotation<'src>

pub fn name_value(&self) -> &str

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

Convenience accessor for self.name.value.

impl DirectiveAnnotation<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this directive 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 directive 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 DirectiveAnnotation<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this directive 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 directive 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 DirectiveAnnotation<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for DirectiveAnnotation<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for DirectiveAnnotation<'src>

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