Struct Argument 

pub struct Argument<'src> {
    pub name: Name<'src>,
    pub span: ByteSpan,
    pub syntax: Option<Box<ArgumentSyntax<'src>>>,
    pub value: Value<'src>,
}

A single argument in a field selection or directive annotation.

See Arguments in the spec.

Fields

name: Name<'src>

span: ByteSpan

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

value: Value<'src>

Implementations

impl<'src> Argument<'src>

pub fn name_value(&self) -> &str

Returns the name of this argument as a string slice.

Convenience accessor for self.name.value.

impl Argument<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this argument’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 argument’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 Argument<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this argument’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 argument’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 Argument<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for Argument<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for Argument<'src>

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