Struct ThresholdConfig 

pub struct ThresholdConfig { /* private fields */ }

An immutable M-of-N threshold configuration.

Construct with ThresholdConfig::new. The configuration validates all inputs at construction time; a successfully constructed value is guaranteed to be internally consistent.

Canonical Address

Every ThresholdConfig has a canonical multisig address derived from the sorted public keys and the (M, N) policy. This address is deterministic and insertion-order-independent, so it can be used as a stable on-chain identifier regardless of how committee members submit their keys.

Implementations

impl ThresholdConfig

pub fn new(required: usize, public_keys: Vec<PublicKey>) -> Result<Self, Error>

Construct a new threshold configuration.

Parameters

• required: M — the number of valid signatures required.
• public_keys: The N committee member public keys, in any order. Each key must be exactly PUBLIC_KEY_BYTES bytes.

Errors

• Error::CommitteeTooSmall if fewer than 2 keys are supplied.
• Error::InvalidThreshold if required is 0 or exceeds the number of keys.
• Error::InvalidPublicKeyLength if any key has an incorrect byte length.

pub fn required(&self) -> usize

The required signature threshold M.

pub fn total(&self) -> usize

The total number of committee members N.

pub fn policy(&self) -> String

A human-readable policy string such as "2-of-3".

pub fn public_keys(&self) -> &[PublicKey]

The ordered list of committee public keys.

pub fn address(&self) -> &MultisigAddress

The canonical multisig address for this committee and policy.

pub fn get_public_key(&self, index: usize) -> Option<&PublicKey>

Return the public key at the given committee index.

Returns None if index >= total.

Trait Implementations

impl Clone for ThresholdConfig

fn clone(&self) -> ThresholdConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThresholdConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ThresholdConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ThresholdConfig

fn eq(&self, other: &ThresholdConfig) -> 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 Serialize for ThresholdConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
