Struct h2::proto::streams::flow_control::Window

pub struct Window(i32);

The current capacity of a flow-controlled Window.

This number can go negative when either side has used a certain amount of capacity when the other side advertises a reduction in size.

This type tries to centralize the knowledge of addition and subtraction to this capacity, instead of having integer casts throughout the source.

0: i32

Implementations

impl Window

pub fn as_size(&self) -> u32

pub fn checked_size(&self) -> u32

pub fn decrease_by(&mut self, other: u32) -> Result<(), Reason>

Trait Implementations

impl Clone for Window

fn clone(&self) -> Window

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Window

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

Formats the value using the given formatter.

impl Display for Window

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

Formats the value using the given formatter.

impl From<Window> for isize

fn from(w: Window) -> isize

Converts to this type from the input type.

impl PartialEq<usize> for Window

fn eq(&self, other: &usize) -> 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.

impl PartialEq for Window

fn eq(&self, other: &Window) -> 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.

impl PartialOrd<usize> for Window

fn partial_cmp(&self, other: &usize) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
