Enum LookAheadValue

pub enum LookAheadValue<'a, S: ScalarValue + 'a> {
    Null,
    Scalar(&'a S),
    Enum(&'a str),
    List(LookAheadList<'a, S>),
    Object(LookAheadObject<'a, S>),
}

JSON-like value performing look-ahead operations on an executed GraphQL query.

In contrast to an InputValue, these values do only contain constants, meaning that GraphQL variables get automatically resolved.

Variants

Null

Scalar(&'a S)

Enum(&'a str)

List(LookAheadList<'a, S>)

Object(LookAheadObject<'a, S>)

Trait Implementations

impl<'a, S: Clone + ScalarValue + 'a> Clone for LookAheadValue<'a, S>

fn clone(&self) -> LookAheadValue<'a, S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, S: Debug + ScalarValue + 'a> Debug for LookAheadValue<'a, S>

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

Formats the value using the given formatter.

impl<'a, S: PartialEq + ScalarValue + 'a> PartialEq for LookAheadValue<'a, S>

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