Trait Implementations

impl Clone for BlockSize

fn clone(&self) -> BlockSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BlockSize

impl Debug for BlockSize

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

Formats the value using the given formatter.

impl Default for BlockSize

fn default() -> BlockSize

Returns the “default value” for a type.

impl Eq for BlockSize

impl PartialEq for BlockSize

fn eq(&self, other: &BlockSize) -> 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.
