Struct SharedRingMpsc 

Source 
pub struct SharedRingMpsc;
Expand description

Factory for an MPSC pool composed from N Lamport SPSC rings.

Implementations§

Source§

impl SharedRingMpsc

Source

pub fn create_anon_pool( n_producers: usize, capacity: usize, ) -> Result<(Vec<MpscProducer>, MpscConsumer), RingError>

Anonymous in-memory pool of N producer rings + one consumer. Skips file create + ftruncate; in-process only.

Source

pub fn create_pool( path_prefix: impl AsRef<Path>, n_producers: usize, capacity: usize, ) -> Result<(Vec<MpscProducer>, MpscConsumer), RingError>

File-backed pool: one file per producer ring. Each ring’s path is derived from path_prefix by appending .{i}.bin.

Source

pub fn open_pool( path_prefix: impl AsRef<Path>, n_producers: usize, expected_capacity: usize, ) -> Result<(Vec<MpscProducer>, MpscConsumer), RingError>

Open an existing file-backed pool. Caller passes the same path_prefix + n_producers + capacity the pool was created with.
