Struct FieldSelection 

pub struct FieldSelection<'src> {
    pub alias: Option<Name<'src>>,
    pub arguments: Vec<Argument<'src>>,
    pub directives: Vec<DirectiveAnnotation<'src>>,
    pub name: Name<'src>,
    pub selection_set: Option<SelectionSet<'src>>,
    pub span: ByteSpan,
    pub syntax: Option<Box<FieldSelectionSyntax<'src>>>,
}

A field selection within a selection set, optionally aliased, with arguments, directives, and a nested selection set.

See Fields in the spec.

Fields

alias: Option<Name<'src>>

arguments: Vec<Argument<'src>>

name: Name<'src>

selection_set: Option<SelectionSet<'src>>

span: ByteSpan

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

Implementations

impl<'src> FieldSelection<'src>

pub fn name_value(&self) -> &str

Returns the name of this field selection as a string slice.

Convenience accessor for self.name.value.

impl FieldSelection<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this field selection’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 field selection’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 FieldSelection<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this field selection’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 field selection’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 FieldSelection<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for FieldSelection<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for FieldSelection<'src>

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