Implementations

impl BufferSize

pub const fn size_in_bytes(&self) -> usize

Get the buffer size in bytes.

Example

use w5500_ll::BufferSize;

assert_eq!(BufferSize::KB0.size_in_bytes(), 0);
assert_eq!(BufferSize::KB1.size_in_bytes(), 1 * 1024);
assert_eq!(BufferSize::KB2.size_in_bytes(), 2 * 1024);
assert_eq!(BufferSize::KB4.size_in_bytes(), 4 * 1024);
assert_eq!(BufferSize::KB8.size_in_bytes(), 8 * 1024);
assert_eq!(BufferSize::KB16.size_in_bytes(), 16 * 1024);

impl Ord for BufferSize

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

impl TryFrom<u8> for BufferSize

fn try_from(val: u8) -> Result<BufferSize, u8>

Get the buffer size given the register value.

Example
