Struct AllowlistStorage 

pub struct AllowlistStorage { /* private fields */ }

Storage backing the per-faucet allowlist.

AllowlistStorage exposes the slot name and schema for the allowed_accounts map plus an optional initial set of allowed accounts. It is not an installable account component on its own — the policy component that installs the storage map (typically super::BasicAllowlist) reads the slot name and the initial entries from here.

Storage

• Self::allowed_accounts_slot(): storage map keyed by account ID (word layout [0, 0, account_id_suffix, account_id_prefix]). An account is considered allowed when its entry is the word [1, 0, 0, 0]; the zero word (including the default for unset entries) means not allowed. This is the opposite of the blocklist default — a faucet with an empty allowlist rejects every transfer.

Implementations

impl AllowlistStorage

pub fn new() -> AllowlistStorage

Creates an AllowlistStorage with no initially allowed accounts.

pub fn with_allowed_accounts( allowed_accounts: impl IntoIterator<Item = AccountId>, ) -> AllowlistStorage

Creates an AllowlistStorage with the given allowed accounts.

Duplicate account IDs are deduplicated by the underlying set.

pub fn allowed_accounts(&self) -> &BTreeSet<AccountId>

Returns the initial allowed accounts captured in this storage.

pub fn allowed_accounts_slot() -> &'static StorageSlotName

Storage slot name for the allowed-accounts map.

pub fn allowed_accounts_slot_schema() -> (StorageSlotName, StorageSlotSchema)

Schema entry for the allowed-accounts map slot (documentation / tooling).

pub fn build_storage_map(&self) -> StorageMap

Builds the initial allowed_accounts StorageMap from the captured set, marking each account ID’s map entry with the [1, 0, 0, 0] allowed-flag word.

pub fn into_slot(self) -> StorageSlot

Consumes the storage and returns the StorageSlot it contributes to an account component. The allowed_accounts map populated with the initial entries.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AllowlistStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl Default for AllowlistStorage

fn default() -> AllowlistStorage

Returns the “default value” for a type.

impl From<AllowlistStorage> for BasicAllowlist
