Struct AccountAccessStructure 

pub struct AccountAccessStructure {
    pub keys: BTreeMap<CredentialIndex, CredentialPublicKeys>,
    pub threshold: NonZeroThresholdU8<AccountKind>,
}

The most straighforward account access structure is a map of public keys with the account threshold.

Fields

keys: BTreeMap<CredentialIndex, CredentialPublicKeys>

Keys indexed by credential.

threshold: NonZeroThresholdU8<AccountKind>

The number of credentials that needed to sign a transaction.

Implementations

impl AccountAccessStructure

pub fn new( account_threshold: NonZeroThresholdU8<AccountKind>, structure: &[(CredentialIndex, NonZeroThresholdU8<SignatureKind>, &[(KeyIndex, VerifyingKey)])], ) -> AccountAccessStructure

Generate a new AccountAccessStructure for the thresholds, public keys, and key indices specified in the input. If there are duplicate indices then later ones override the previous ones.

pub fn singleton(public_key: VerifyingKey) -> AccountAccessStructure

Generate a new AccountAccessStructure with a single credential and public key, at credential and key indices 0.

impl AccountAccessStructure

pub fn num_keys(&self) -> u32

Return the total number of keys present in the access structure.

Trait Implementations

impl Clone for AccountAccessStructure

fn clone(&self) -> AccountAccessStructure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountAccessStructure

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

Formats the value using the given formatter.

impl Deserial for AccountAccessStructure

fn deserial<R>(source: &mut R) -> Result<AccountAccessStructure, Error>

where R: ReadBytesExt,

impl Deserial for AccountAccessStructure

fn deserial<__R>( ________________source: &mut __R, ) -> Result<AccountAccessStructure, ParseError>

where __R: Read,

Attempt to read a structure from a given source, failing if an error occurs during deserialization or reading.

impl From<&AccountInfo> for AccountAccessStructure

fn from(value: &AccountInfo) -> AccountAccessStructure

Converts to this type from the input type.

impl From<&AccountKeys> for AccountAccessStructure

fn from(value: &AccountKeys) -> AccountAccessStructure

Converts to this type from the input type.

impl HasAccountAccessStructure for AccountAccessStructure

fn threshold(&self) -> NonZeroThresholdU8<AccountKind>

The number of credentials that must sign a transaction.

fn credential_keys(&self, idx: CredentialIndex) -> Option<&CredentialPublicKeys>

Access a credential at the provided index.

impl PartialEq for AccountAccessStructure

fn eq(&self, other: &AccountAccessStructure) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serial for AccountAccessStructure

fn serial<B>(&self, out: &mut B)

where B: Buffer,

impl Serial for AccountAccessStructure

fn serial<W>(&self, out: &mut W) -> Result<(), <W as Write>::Err>

where W: Write,

Attempt to write the structure into the provided writer, failing if only part of the structure could be written.
