Struct WindowScale

pub struct WindowScale(/* private fields */);

This type is a witness for a valid window scale exponent value.

Per RFC 7323 Section 2.2, the restriction is as follows: The maximum scale exponent is limited to 14 for a maximum permissible receive window size of 1 GiB (2^(14+16)).

Implementations

impl WindowScale

pub const MAX: WindowScale = _

The largest possible WindowScale.

pub const ZERO: WindowScale = _

The smallest possible WindowScale.

pub fn new(ws: u8) -> Option<Self>

Creates a new WindowScale.

Returns None if the input exceeds the maximum possible value.

pub fn get(&self) -> u8

Returns the inner value.

Trait Implementations

impl Clone for WindowScale

fn clone(&self) -> WindowScale

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowScale

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

Formats the value using the given formatter.

impl Default for WindowScale

fn default() -> WindowScale

Returns the “default value” for a type.

impl PartialEq for WindowScale

fn eq(&self, other: &WindowScale) -> 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 Shl<WindowScale> for UnscaledWindowSize

type Output = WindowSize

The resulting type after applying the << operator.

fn shl(self, WindowScale: WindowScale) -> Self::Output

Performs the << operation.

impl Shr<WindowScale> for WindowSize

type Output = UnscaledWindowSize

The resulting type after applying the >> operator.

fn shr(self, WindowScale: WindowScale) -> Self::Output

Performs the >> operation.
