Struct NoId 

pub struct NoId;

Zero-sized placeholder used when a key component is a compile-time constant.

NoId is the PkId or SkId type parameter of KeyId for item types whose partition key or sort key is a constant (e.g. singleton items like the PlatformConfig in the crate examples). It carries no data because the key value is baked into the type’s HasConstAttribute impl.

You will encounter NoId as part of KeyId::NONE for singleton items, and as the SkId of KeyId::pk for items with a variable PK but a constant SK.

Examples

use dynamodb_facade::{KeyId, NoId};

// Singleton item — both PK and SK are constants.
let key_id: KeyId<NoId, NoId> = KeyId::NONE;

// Variable PK, constant SK — SkId is NoId.
let key_id: KeyId<&str, NoId> = KeyId::pk("user-1");
