Struct Directives

pub struct Directives<'a> {
    pub children: Vec<'a, Directive<'a>>,
}

AST Node for lists of GraphQL Directives, which provide a way to describe alternate behavior in GraphQL.

Typical directives that occur in queries are for example @skip, @include, and @defer`. Reference

Fields

children: Vec<'a, Directive<'a>>

Implementations

impl<'a> Directives<'a>

pub fn is_empty(&self) -> bool

Checks whether this list of Directives contains any values.

Trait Implementations

impl<'a> Clone for Directives<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Directives<'a>

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

Formats the value using the given formatter.

impl<'a> DefaultIn<'a> for Directives<'a>

fn default_in(arena: &'a Bump) -> Self

impl<'a> IntoIterator for Directives<'a>

type Item = Directive<'a>

The type of the elements being iterated over.

type IntoIter = IntoIter<'a, Directive<'a>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> PartialEq for Directives<'a>

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