Struct FieldDefinition 

pub struct FieldDefinition<'src> {
    pub parameters: Vec<InputValueDefinition<'src>>,
    pub description: Option<StringValue<'src>>,

    pub field_type: TypeAnnotation<'src>,
    pub name: Name<'src>,
    pub span: ByteSpan,

}

A field definition within an object type or interface type.

See Field Definitions in the spec.

Implementations

impl<'src> FieldDefinition<'src>

pub fn name_value(&self) -> &str

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

Convenience accessor for self.name.value.

impl FieldDefinition<'_>

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

See AstNode::append_source().

pub fn byte_span(&self) -> ByteSpan

Returns this field 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 field 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 FieldDefinition<'_>

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

See AstNode::append_source().

fn byte_span(&self) -> ByteSpan

Returns this field 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 field 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 FieldDefinition<'src>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'src> Debug for FieldDefinition<'src>

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

Formats the value using the given formatter.

impl<'src> PartialEq for FieldDefinition<'src>

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