NonceManager

nautilus_derive::signing::nonce

Struct NonceManager 

Source 
pub struct NonceManager;
Expand description

Thread-safe process-wide nonce allocator keyed by (wallet, subaccount_id).

Implementations§

Source§

impl NonceManager

Source

pub fn new() -> Self

Constructs a manager backed by the process-wide nonce registry.

Source

pub fn next_nonce( &self, wallet: &str, subaccount_id: u64, ) -> Result<u64, NonceError>

Allocates the next nonce for (wallet, subaccount_id) using the system clock as the nanosecond reference.

§Errors

Returns an error if the system clock is invalid, the timestamp cannot be encoded, or rollback places the nonce outside the order window.

Source

pub fn next_nonce_at( &self, wallet: &str, subaccount_id: u64, now_ns: u64, ) -> Result<u64, NonceError>

Allocates the next nonce for (wallet, subaccount_id) with caller-supplied UNIX time in nanoseconds.

§Errors

Returns an error if overflow occurs or rollback places the next nonce outside the inclusive order window.

Source

pub fn last_issued(&self, wallet: &str, subaccount_id: u64) -> Option<u64>

Returns the most recently issued nonce for a key, if any.
