Struct OperationDefinition 

pub struct OperationDefinition<'src> {
    pub description: Option<StringValue<'src>>,
    pub directives: Vec<DirectiveAnnotation<'src>>,
    pub name: Option<Name<'src>>,
    pub operation_kind: OperationKind,

    pub shorthand: bool,
    pub span: ByteSpan,

}

An operation definition (query, mutation, or subscription).

See Operations in the spec.

Fields

description: Option<StringValue<'src>>

directives: Vec<DirectiveAnnotation<'src>>

name: Option<Name<'src>>

operation_kind: OperationKind

selection_set: SelectionSet<'src>

shorthand: bool

true for shorthand queries ({ field }) that omit the query keyword.

span: ByteSpan

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

variable_definitions: Vec<VariableDefinition<'src>>

Implementations

impl<'src> OperationDefinition<'src>

pub fn name_value(&self) -> Option<&str>

Returns the operation name as a string slice, or None for anonymous (shorthand) operations.

Convenience accessor for self.name.

impl OperationDefinition<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this operation’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 operation’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 OperationDefinition<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this operation’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 operation’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 OperationDefinition<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for OperationDefinition<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for OperationDefinition<'src>

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