SemaphoreLimiter

cognee_lib::core

Struct SemaphoreLimiter 

Source 
pub struct SemaphoreLimiter { /* private fields */ }
Expand description

Admission-style concurrency limit: at most max_per_sec starts may be issued per second.

Distinct from Pipeline::with_concurrency, which bounds data-item parallelism at the executor level. SemaphoreLimiter is a proactive request-rate throttle implemented as a token bucket whose capacity and refill rate are both set to max_per_sec.

Implementations§

Source§

impl SemaphoreLimiter

Source

pub fn new(max_per_sec: usize) -> SemaphoreLimiter
