Struct BlockDescriptorFlags 

pub struct BlockDescriptorFlags(pub u32);

Flags on a block descriptor.

Tuple Fields

0: u32

Implementations

impl BlockDescriptorFlags

pub const FORWARDER: u32 = 0x01

Forwarder — maps to the next block’s original offset.

pub const OVERLAY: u32 = 0x02

Overlay — the allocation bitmap defines how the block is filled.

pub const NOT_USED: u32 = 0x04

Not used — the block is ignored.

pub fn bits(self) -> u32

The raw flag bits.

pub fn contains(self, flag: u32) -> bool

Whether any of the given flag bits are set.

pub fn is_forwarder(self) -> bool

Whether the forwarder flag is set.

pub fn is_overlay(self) -> bool

Whether the overlay flag is set.

pub fn is_not_used(self) -> bool

Whether the not-used flag is set.

Trait Implementations

impl Clone for BlockDescriptorFlags

fn clone(&self) -> BlockDescriptorFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BlockDescriptorFlags

impl Debug for BlockDescriptorFlags

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

Formats the value using the given formatter.

impl Eq for BlockDescriptorFlags

impl PartialEq for BlockDescriptorFlags

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