Trait KeySchema

Source

pub trait KeySchema: ValidKeySchema<Self::Kind> {
    type Kind: KeySchemaKind;
    type PartitionKey: AttributeDefinition;
}

Expand description

Defines the key schema for a DynamoDB table or index.

A key schema specifies the partition key attribute and the key kind (SimpleKey or CompositeKey). Implementations are generated by key_schema!, table_definitions!, and index_definitions! — you rarely implement this trait manually.

For composite key schemas, also implement CompositeKeySchema to expose the sort key type. For simple key schemas, also implement SimpleKeySchema.

§Examples

use dynamodb_facade::{KeySchema, TableSchema};

fn _assert<KS: KeySchema>() {}
// PlatformTable's KeySchema associated type implements the KeySchema trait.
_assert::<TableSchema<PlatformTable>>();
