Struct WindowState 

pub struct WindowState {
    pub window: usize,
    pub window_max: usize,
    pub window_min: usize,
    pub window_flexibility: usize,
    pub fast_rate_rounds: usize,
    pub very_slow_rate_rounds: usize,
}

Window adaptation state for resource transfers.

Tracks window size, min/max bounds, and rate detection for fast/very-slow link adaptation.

Fields

window: usize

window_max: usize

window_min: usize

window_flexibility: usize

fast_rate_rounds: usize

very_slow_rate_rounds: usize

Implementations

impl WindowState

pub fn new() -> Self

pub fn restore(&mut self, previous_window: usize)

Restore window state from a previous transfer on the same link.

pub fn on_window_complete(&mut self)

Called when all outstanding parts in the window are received. Grows window and ratchets window_min.

pub fn on_timeout(&mut self)

Called on timeout waiting for parts. Shrinks window, shrinks window_max (can decrease by 2).

pub fn update_req_resp_rate(&mut self, rate: f64)

Update rate tracking based on measured req_resp_rtt_rate. Called after first part of a window is received.

pub fn update_data_rate(&mut self, rate: f64)

Update rate tracking based on measured data RTT rate. Called after a full window of parts is received.

Trait Implementations

impl Clone for WindowState

fn clone(&self) -> WindowState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowState

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

Formats the value using the given formatter.
