pub enum BlockState {
    Unallocated,

Unmarked

the block is allocated but not marked.

Marked

the block is allocated and marked.

Reusable

Fields

unavailable_lines: u8

Test if the block is reuasable.

Trait Implementations

impl Clone for BlockState

fn clone(&self) -> BlockState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockState

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

Formats the value using the given formatter.

impl From<BlockState> for u8

fn from(state: BlockState) -> Self

Converts to this type from the input type.

impl From<u8> for BlockState

fn from(state: u8) -> Self

Converts to this type from the input type.

impl PartialEq for BlockState

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
