Struct OperationDefinition

pub struct OperationDefinition<'a> {
    pub operation: OperationKind,
    pub name: Option<NamedType<'a>>,
    pub variable_definitions: VariableDefinitions<'a>,
    pub directives: Directives<'a>,
    pub selection_set: SelectionSet<'a>,
}

AST Node for an Operation Definition, which defines the entrypoint for GraphQL’s execution.

Reference

Fields

operation: OperationKind

The kind of operation that this definition specifies

name: Option<NamedType<'a>>

variable_definitions: VariableDefinitions<'a>

A list of variables that the operation defines and accepts during execution.

When an Operation Definition defines no variables this may be an empty list, as can be checked using Directives::is_empty.

directives: Directives<'a>

Directives that are annotating this Operation Definition.

When no Directives are present, this will be an empty list, as can be checked using Directives::is_empty. See: Directives

selection_set: SelectionSet<'a>

A sub-Selection Set that is applied when this Operation Definition is executed to the root type of the specified kind of operation. See: SelectionSet

Trait Implementations

impl<'a> Clone for OperationDefinition<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for OperationDefinition<'a>

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

Formats the value using the given formatter.

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 OperationDefinition<'a>

fn eq(&self, other: &OperationDefinition<'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 OperationDefinition<'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 OperationDefinition<'arena>

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