Enum ReservedNameContext 

pub enum ReservedNameContext {
    FragmentName,
    EnumValue,
}

Contexts where certain names are reserved in GraphQL.

Some names have special meaning in specific contexts and cannot be used as identifiers there. This enum is used by GraphQLParseErrorKind::ReservedName to indicate which context rejected the name.

Variants

FragmentName

Fragment names cannot be on (it introduces the type condition).

Invalid: fragment on on User { ... } The first on would be parsed as the fragment name, but on is reserved in this context.

EnumValue

Enum values cannot be true, false, or null.

Invalid: enum Bool { true false } or enum Maybe { null some } These would be ambiguous with boolean/null literals in value contexts.

Trait Implementations

impl Clone for ReservedNameContext

fn clone(&self) -> ReservedNameContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReservedNameContext

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

Formats the value using the given formatter.

impl PartialEq for ReservedNameContext

fn eq(&self, other: &ReservedNameContext) -> 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.
