pub struct BlocklistStorage { /* private fields */ }Expand description
Storage backing the per-faucet blocklist.
BlocklistStorage exposes the slot name and schema for the blocked_accounts map plus an
optional initial set of blocked accounts. It is not an installable account component on
its own — the policy component that installs the storage map (typically
super::BasicBlocklist) reads the slot name and the initial entries from here.
The low-level block_account / unblock_account / is_blocked / assert_not_blocked
procedures live in the standards library at
miden::standards::faucets::policies::transfer::blocklist as Invocation: exec helpers —
they perform no authorization and must be wrapped by an auth-checking admin component (see
BlocklistOwnerControlled) before being exposed on a faucet.
§Storage
Self::blocked_accounts_slot(): storage map keyed by account ID (word layout[0, 0, account_id_suffix, account_id_prefix]). An account is considered blocked when its entry is the word[1, 0, 0, 0]; the zero word (including the default for unset entries) means not blocked.
Implementations§
Source§impl BlocklistStorage
impl BlocklistStorage
Sourcepub fn new() -> BlocklistStorage
pub fn new() -> BlocklistStorage
Creates a BlocklistStorage with no initially blocked accounts.
Sourcepub fn with_blocked_accounts(
blocked_accounts: impl IntoIterator<Item = AccountId>,
) -> BlocklistStorage
pub fn with_blocked_accounts( blocked_accounts: impl IntoIterator<Item = AccountId>, ) -> BlocklistStorage
Creates a BlocklistStorage with the given blocked accounts.
Duplicate account IDs are deduplicated by the underlying set.
Sourcepub fn blocked_accounts(&self) -> &BTreeSet<AccountId>
pub fn blocked_accounts(&self) -> &BTreeSet<AccountId>
Returns the initial blocked accounts captured in this storage.
Sourcepub fn blocked_accounts_slot() -> &'static StorageSlotName
pub fn blocked_accounts_slot() -> &'static StorageSlotName
Storage slot name for the blocked-accounts map.
Sourcepub fn blocked_accounts_slot_schema() -> (StorageSlotName, StorageSlotSchema)
pub fn blocked_accounts_slot_schema() -> (StorageSlotName, StorageSlotSchema)
Schema entry for the blocked-accounts map slot (documentation / tooling).
Sourcepub fn build_storage_map(&self) -> StorageMap
pub fn build_storage_map(&self) -> StorageMap
Builds the initial blocked_accounts StorageMap from the captured set, marking each
account ID’s map entry with the [1, 0, 0, 0] blocked-flag word.
Sourcepub fn into_slot(self) -> StorageSlot
pub fn into_slot(self) -> StorageSlot
Consumes the storage and returns the StorageSlot it contributes to an account
component. The blocked_accounts map populated with the initial entries.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
