Struct MaxEthernetFrameSize

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

The maximum frame size one ethernet device can send.

The frame size includes the ethernet header, the data payload, but excludes the 4 bytes from FCS (frame check sequence) as we don’t calculate CRC and it is normally handled by the device.

Implementations

impl MaxEthernetFrameSize

pub const MIN: MaxEthernetFrameSize = _

The minimum ethernet frame size.

We don’t care about FCS, so the minimum frame size for us is 64 - 4.

pub const fn new(frame_size: u32) -> Option<MaxEthernetFrameSize>

Creates from the maximum size of ethernet header and ethernet payload, checks that it is valid, i.e., larger than the minimum frame size.

pub const fn as_mtu(&self) -> Mtu

Converts the maximum frame size to its corresponding MTU.

pub const fn from_mtu(mtu: Mtu) -> Option<MaxEthernetFrameSize>

Creates the maximum ethernet frame size from MTU.

Trait Implementations

impl Clone for MaxEthernetFrameSize

fn clone(&self) -> MaxEthernetFrameSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MaxEthernetFrameSize

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

Formats the value using the given formatter.

impl Ord for MaxEthernetFrameSize

fn cmp(&self, other: &MaxEthernetFrameSize) -> 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.

impl PartialEq for MaxEthernetFrameSize

fn eq(&self, other: &MaxEthernetFrameSize) -> 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 for MaxEthernetFrameSize

fn partial_cmp(&self, other: &MaxEthernetFrameSize) -> 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.
