Enum Definition 

pub enum Definition<'src> {
    DirectiveDefinition(DirectiveDefinition<'src>),
    FragmentDefinition(FragmentDefinition<'src>),
    OperationDefinition(OperationDefinition<'src>),
    SchemaDefinition(SchemaDefinition<'src>),
    SchemaExtension(SchemaExtension<'src>),
    TypeDefinition(TypeDefinition<'src>),
    TypeExtension(TypeExtension<'src>),
}

A top-level definition in a GraphQL document.

Covers both type-system definitions (schema, types, directives, extensions) and executable definitions (operations, fragments).

See Document in the spec.

Implementations

impl<'src> Definition<'src>

pub fn description(&self) -> Option<&StringValue<'src>>

Returns the description string for this definition, if one is present.

pub fn directive_annotations(&self) -> &[DirectiveAnnotation<'src>]

Returns the directive annotations applied to this definition.

pub fn name(&self) -> Option<&Name<'src>>

Returns the Name of this definition, or None for schema definitions/extensions (which have no name).

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

Returns the name of this definition as a string slice, or None for unnamed definitions (schema definitions/extensions, anonymous operations).

Convenience accessor for self.name().value.

impl Definition<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this 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 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 Definition<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this 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 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 Definition<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for Definition<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for Definition<'src>

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