Struct PoolConfig 

pub struct PoolConfig {
    pub policy: ChunkPolicy,
    pub pause_after_failures: u32,
    pub retire_after_failures: u32,
    pub backoff_initial: Duration,
    pub backoff_max: Duration,
}

Failure handling and chunk sizing for a LanePool.

Fields

policy: ChunkPolicy

How chunks are sized from each lane’s rate.

pause_after_failures: u32

Consecutive failed chunks a lane may have before it starts pausing between attempts (1: pause after every failure). A single dropped connection is common enough that retrying at once is often right.

retire_after_failures: u32

Consecutive failed chunks after which a lane is retired for the rest of the epoch. u32::MAX never retires.

backoff_initial: Duration

The first pause; each further consecutive failure doubles it.

backoff_max: Duration

The longest pause.

Implementations

impl PoolConfig

pub const EXPORT: Self

Still export / tilt video: 22 s chunks, pause from the 2nd consecutive failure (15 s doubling to 120 s, the desktop export’s schedule), retire after 5.

pub const INTERACTIVE: Self

Interactive requests: 1.5 s chunks, short pauses (250 ms to 2 s), retire after 3.

pub fn backoff(&self, consecutive_failures: u32) -> Duration

The pause after consecutive_failures failed chunks in a row: zero below Self::pause_after_failures, then backoff_initial doubling per further failure, capped at backoff_max.
