Struct RedLockHelper 

pub struct RedLockHelper;

Helper functions for RedLock algorithm.

Implementations

impl RedLockHelper

pub fn has_sufficient_successes( success_count: usize, database_count: usize, ) -> bool

Checks if we have sufficient successes for majority consensus.

For N servers, we need at least (N/2 + 1) successes.

pub fn has_too_many_failures_or_faults( failure_or_fault_count: usize, database_count: usize, ) -> bool

Checks if we have too many failures/faults to achieve majority.

For odd N: need (N/2 + 1) failures to rule out majority. For even N: need (N/2 + 1) failures to rule out majority.

pub fn create_lock_id() -> String

Generates a unique lock ID.

Format: {process_id}_{counter}_{random_uuid}

pub fn now_millis() -> u64

Gets current time in milliseconds since Unix epoch.
