Struct Aimd 

pub struct Aimd { /* private fields */ }

Available on crate feature adaptive only.

Additive-increase, multiplicative-decrease.

On success — but only while the limit is actually being used — the limit grows by a fixed step; on failure it is cut by a multiplier. The classic congestion response: probe upward gently, retreat sharply.

Examples

use throttle_net::{Aimd, AdaptiveLimiter};

// Grow by 1 on a saturated success, halve on failure; limit in [4, 200].
let limiter = AdaptiveLimiter::builder()
    .floor(4)
    .ceiling(200)
    .build(Aimd::new(1, 0.5));

Implementations

impl Aimd

pub fn new(increase: u32, decrease: f64) -> Self

Increase the limit by increase per saturated success; multiply by decrease (in (0.0, 1.0]) on failure.

Trait Implementations

impl AdaptiveStrategy for Aimd

fn adjust(&self, current: u32, in_flight: u32, outcome: Outcome) -> u32

Returns the proposed new limit given the current limit, the in_flight count at the time of the observation (including the just-finished request), and the outcome.

impl Clone for Aimd

fn clone(&self) -> Aimd

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Aimd

impl Debug for Aimd

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Aimd

fn default() -> Self

Increase by 1, halve on failure.
