Enum FieldKind 

pub(crate) enum FieldKind<'a> {
    Slot(&'a Type),
    Mapping {
        key: &'a Type,
        value: &'a Type,
    },
    NestedMapping {
        key1: &'a Type,
        key2: &'a Type,
        value: &'a Type,
    },
}

Classification of a field based on its type

Variants

Slot(&'a Type)

Fields with a direct slot allocation, either single or multi (Slot<V>).

Mapping

Single-level mapping (Mapping<K, V>)

Fields

key: &'a Type

value: &'a Type

NestedMapping

Nested mapping (Mapping<K1, Mapping<K2, V>>)

Fields

key1: &'a Type

key2: &'a Type

value: &'a Type

Trait Implementations

impl<'a> Clone for FieldKind<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for FieldKind<'a>

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

Formats the value using the given formatter.

impl<'a> Copy for FieldKind<'a>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
