Role-based access control

Required Associated Types

type Role: BorshSerialize + IntoStorageKey

Roles type (probably an enum).

Provided Methods

fn root() -> Slot<()>

Storage slot namespace for items.

fn slot_members_of(role: &Self::Role) -> Slot<UnorderedSet<AccountId>>

Storage slot for the backing UnorderedSet of all accounts assigned to a role.

fn with_members_of<T>(
role: &Self::Role,
f: impl FnOnce(&mut UnorderedSet<AccountId>) -> T
) -> T

Deserializes the backing UnorderedSet structure, executes predicate f on it, and reserializes the structure, returning the return value of f.

fn iter_members_of(role: &Self::Role) -> Iter ⓘ

Iterates over all accounts that have been assigned a role.

fn has_role(account_id: &AccountId, role: &Self::Role) -> bool

Returns whether a given account has been given a certain role.

fn add_role(&mut self, account_id: AccountId, role: &Self::Role)

Assigns a role to an account.

fn remove_role(&mut self, account_id: &AccountId, role: &Self::Role)

Removes a role from an account.

fn require_role(role: &Self::Role)

Requires transaction predecessor to have a given role.

fn prohibit_role(role: &Self::Role)

Requires transaction predecessor to not have a given role.
