Struct OwnerConfigNote 

pub struct OwnerConfigNote { /* private fields */ }

An OwnerConfig note: triggers an Ownable2Step management action on the account that consumes it.

A single note script dispatches on a selector in the note’s storage to one of the component’s management procedures (transfer_ownership, accept_ownership, renounce_ownership). All authorization is enforced by those procedures against the note sender, so the note carries no assets and its authorization is bound to sender at creation time.

The note is always public and tagged for account — the account carrying the Ownable2Step component whose ownership state is being managed. The sender is the account authorized for the selected action: the current owner for TransferOwnership / RenounceOwnership, or the nominated owner for AcceptOwnership.

The note is bound to the target account by a NetworkAccountTarget attachment: the script asserts that the consuming account matches that target before dispatching, so the note cannot be consumed by a third-party account that merely accepts its sender. The binding also makes the note a valid AccountTargetNetworkNote, routing it to account for network execution.

Construct one with the builder; convert it into a protocol Note infallibly via Note::from.

Implementations

impl OwnerConfigNote

pub fn builder() -> OwnerConfigNoteBuilder

Builds a new OwnerConfigNote that applies config to account.

The note is bound to account by a NetworkAccountTarget attachment that the builder appends unless the caller already supplied one for account.

Errors

Returns an error if:

• account is not a public account (the note is bound to it via a NetworkAccountTarget, which requires a public target).
• the attachments carry a NetworkAccountTarget for an account other than account.
• the attachments exceed their protocol limit (see NoteAttachments::new); the target attachment occupies one of the available slots when the caller does not supply it.

impl OwnerConfigNote

pub const MAX_NUM_STORAGE_ITEMS: usize = 3

Upper bound on the number of storage items of an OwnerConfig note.

The layout is variable: TransferOwnership uses 3 items ([selector, new_owner_suffix, new_owner_prefix]), while AcceptOwnership / RenounceOwnership use 1 ([selector]).

pub fn script() -> NoteScript

Returns the script of the OwnerConfig note.

pub fn script_root() -> NoteScriptRoot

Returns the OwnerConfig note script root.

pub fn sender(&self) -> AccountId

Returns the account ID of the note’s sender (the account authorized for the action).

pub fn account(&self) -> AccountId

Returns the account ID of the managed account (the account the note is tagged for).

pub fn config(&self) -> OwnerConfig

Returns the management action carried by the note.

pub fn serial_number(&self) -> Word

Returns the note’s serial number.

pub fn attachments(&self) -> &NoteAttachments

Returns the attachments carried by the note, which always include a NetworkAccountTarget.

Trait Implementations

impl Clone for OwnerConfigNote

fn clone(&self) -> OwnerConfigNote

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

Performs copy-assignment from source.

impl Debug for OwnerConfigNote

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