Implementations

impl BufSize

pub fn get(&self) -> Option<usize>

Trait Implementations

impl Clone for BufSize

fn clone(&self) -> BufSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BufSize

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

Formats the value using the given formatter.

impl Default for BufSize

fn default() -> Self

Returns the “default value” for a type.

impl From<Option<usize>> for BufSize

fn from(value: Option<usize>) -> Self

Converts to this type from the input type.

impl From<f64> for BufSize

fn from(scale: f64) -> Self

Converts to this type from the input type.

impl From<usize> for BufSize

fn from(value: usize) -> Self

Converts to this type from the input type.

impl PartialEq for BufSize

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