Enum ShapeKey 

pub enum ShapeKey {
    Scalar(ScalarKind, bool),
    Ref,
    Any,
}

A field’s target-blind shape: Scalar(kind, nullable), Ref (the target record’s name is deliberately excluded – see the module doc comment), or Any.

Variants

Scalar(ScalarKind, bool)

A scalar shape with kind and nullability.

Ref

A reference to a record in the environment.

Any

An any type slot.

Trait Implementations

impl Clone for ShapeKey

fn clone(&self) -> ShapeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeKey

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

Formats the value using the given formatter.

impl Eq for ShapeKey

impl Hash for ShapeKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ShapeKey

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