Struct SizeClass 

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

A buffer size class: a power of two from 1 KiB to 1 MiB.

use net_io::SizeClass;
assert_eq!(SizeClass::MEDIUM.bytes(), 16 * 1024);
assert!(SizeClass::new(3000).is_err());
assert_eq!(SizeClass::new(2048).unwrap().bytes(), 2048);

Implementations

impl SizeClass

pub const SMALL: SizeClass

4 KiB.

pub const MEDIUM: SizeClass

16 KiB.

pub const LARGE: SizeClass

64 KiB.

pub const fn new(bytes: u32) -> Result<SizeClass, NetError>

A class of bytes.

Errors

InvalidConfig { field: "size_class" } unless bytes is a power of two from 1 KiB to 1 MiB.

pub const fn bytes(self) -> u32

The size in bytes.

impl Ord for SizeClass

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for SizeClass

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SizeClass

fn partial_cmp(&self, other: &Self) -> 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
