Struct FlowControl 

pub struct FlowControl { /* private fields */ }

Flow-Control-Window mit signed-i64 (Spec §6.9: kann transient negativ werden, wenn Settings das Window verkleinern).

Implementations

impl FlowControl

pub fn new(initial: i64) -> Self

Konstruktor mit Initial-Window-Size.

pub fn window(&self) -> i64

Aktuelles Window.

pub fn consume(&mut self, n: u32) -> Result<(), Http2Error>

Konsumiert n Bytes vom Window. Spec §6.9.1.

Errors

FlowControlExceeded wenn das Window negativ wuerde.

pub fn apply_window_update(&mut self, increment: u32) -> Result<(), Http2Error>

Wendet einen WINDOW_UPDATE an. Spec §6.9.1.

Errors

Protocol(FlowControlError) wenn das Window 2^31-1 ueberschreitet.

pub fn apply_initial_window_size_change(&mut self, old: i64, new: i64)

Anwendung einer neuen INITIAL_WINDOW_SIZE aus SETTINGS-Update (Spec §6.9.2): das Window wird um die Differenz angepasst.

Trait Implementations

impl Clone for FlowControl

fn clone(&self) -> FlowControl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowControl

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

Formats the value using the given formatter.

impl Default for FlowControl

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FlowControl

fn eq(&self, other: &FlowControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
