Struct Config 

pub struct Config {
    pub max_topics: u32,
    pub block_count: u32,
    pub block_size: u32,
    pub ring_depth: u32,
    pub heartbeat_interval: Duration,
    pub stale_timeout: Duration,
}

Configuration for pool-backed O(1) pub/sub.

Fields

max_topics: u32

Maximum number of topics (default: 16).

block_count: u32

Number of blocks in the shared pool (default: 256).

block_size: u32

Size of each block in bytes (default: 65536 = 64 KiB). Usable data capacity is block_size - 8 (8 bytes for refcount header).

ring_depth: u32

Ring depth per topic – how many published samples the ring remembers before overwriting (default: 8). Must be a power of 2.

heartbeat_interval: Duration

Heartbeat write interval (default: 100 ms).

stale_timeout: Duration

Publisher considered dead after this duration without heartbeat (default: 5 s).
