Implementations

impl<'a> Definition<'a>

pub fn operation(&'a self) -> Option<&'a OperationDefinition<'a>>

Helper method to return the OperationDefinition if the Definition is an OperationDefinition.

pub fn fragment(&'a self) -> Option<&'a FragmentDefinition<'a>>

Helper method to return the FragmentDefinition if the Definition is a FragmentDefinition.

Trait Implementations

impl<'a> Clone for Definition<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Definition<'a>

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

Formats the value using the given formatter.

impl<'a> From<FragmentDefinition<'a>> for Definition<'a>

fn from(x: FragmentDefinition<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<OperationDefinition<'a>> for Definition<'a>

fn from(x: OperationDefinition<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for Definition<'a>

fn eq(&self, other: &Definition<'a>) -> 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.

impl<'a> PrintNode for Definition<'a>

fn write_to_buffer(&self, level: usize, buffer: &mut dyn Write) -> Result

Write an AST node to a buffer implementing the Write trait.

fn print(&self) -> String

Print an AST Node to source text as a String allocated on the heap.

impl<'arena> WithDirectives<'arena> for Definition<'arena>

fn directives(&self) -> &Directives<'arena>

Helper method to get all Directives for a given definition directly.

Any Definition AST node may carry Directives, so when those are checked it’s unnecessary to first match the type of Definition.

impl<'a> StructuralPartialEq for Definition<'a>
