Trait CompositeKeySchema 

Source 
pub trait CompositeKeySchema: KeySchema<Kind = CompositeKey> {
    type SortKey: AttributeDefinition;
}
Expand description

A KeySchema with both a partition key and a sort key.

Implemented automatically by key_schema!, table_definitions! and index_definitions! when both PartitionKey and SortKey are declared. Tables and indexes with this schema expose sort-key methods on their query builders (e.g. sk_eq, sk_begins_with).

§Examples

use dynamodb_facade::{CompositeKeySchema, TableSchema};

fn _assert_composite<KS: CompositeKeySchema>() {}
// PlatformTable's key schema has both PK and SK.
_assert_composite::<TableSchema<PlatformTable>>();

Required Associated Types§

Source

type SortKey: AttributeDefinition

The sort key attribute definition.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
