Struct DirectiveDefinition 

pub struct DirectiveDefinition<'src> {
    pub arguments: Vec<InputValueDefinition<'src>>,
    pub description: Option<StringValue<'src>>,
    pub locations: Vec<DirectiveLocation<'src>>,
    pub name: Name<'src>,
    pub repeatable: bool,
    pub span: ByteSpan,
    pub syntax: Option<Box<DirectiveDefinitionSyntax<'src>>>,
}

A directive definition.

See Directive Definitions in the spec.

Spec invariant

The spec grammar requires at least one directive location. For a spec-valid node, locations is always non-empty.

Fields

arguments: Vec<InputValueDefinition<'src>>

description: Option<StringValue<'src>>

locations: Vec<DirectiveLocation<'src>>

name: Name<'src>

repeatable: bool

span: ByteSpan

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

Implementations

impl<'src> DirectiveDefinition<'src>

pub fn name_value(&self) -> &str

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

Convenience accessor for self.name.value.

impl DirectiveDefinition<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this directive 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 directive 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 DirectiveDefinition<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this directive 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 directive 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 DirectiveDefinition<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for DirectiveDefinition<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for DirectiveDefinition<'src>

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