      description: >-
        NEAR Account Identifier.


        This is a unique, syntactically valid, human-readable account identifier
        on the NEAR network.


        [See the crate-level docs for information about
        validation.](index.html#account-id-rules)


        Also see [Error kind precedence](AccountId#error-kind-precedence).


        ## Examples


        ```

        use near_account_id::AccountId;


        let alice: AccountId = "alice.near".parse().unwrap();


        assert!("ƒelicia.near".parse::<AccountId>().is_err()); // (ƒ is not f)

        ```

    ShardId:
      description: >-
        The shard identifier. It may be an arbitrary number - it does not need
        to be

        a number in the range 0..NUM_SHARDS. The shard ids do not need to be

        sequential or contiguous.


        The shard id is wrapped in a new type to prevent the old pattern of
        using

        indices in range 0..NUM_SHARDS and casting to ShardId. Once the
        transition

        if fully complete it potentially may be simplified to a regular type
        alias.
