Struct CompatibleFeatures 

pub struct CompatibleFeatures { /* private fields */ }

Bitmask of compatible features. An implementation can safely ignore any unknown bits that are set.

Implementations

impl CompatibleFeatures

pub const fn new() -> Self

Returns an instance with zero initialized data.

impl CompatibleFeatures

pub const fn into_bytes(self) -> [u8; 8]

Returns the underlying bits.

Layout

The returned byte array is layed out in the same way as described here.

pub const fn from_bytes(bytes: [u8; 8]) -> Self

Converts the given bytes directly into the bitfield struct.

impl CompatibleFeatures

pub fn lazy_refcount(&self) -> <bool as Specifier>::InOut

Returns the value of lazy_refcount. Lazy refcounts bit. If this bit is set then lazy refcount updates can be used. This means marking the image file dirty and postponing refcount metadata updates.

pub fn lazy_refcount_or_err( &self, ) -> Result<<bool as Specifier>::InOut, InvalidBitPattern<<bool as Specifier>::Bytes>>

Returns the value of lazy_refcount.

#Errors

If the returned value contains an invalid bit pattern for lazy_refcount. Lazy refcounts bit. If this bit is set then lazy refcount updates can be used. This means marking the image file dirty and postponing refcount metadata updates.

pub fn with_lazy_refcount(self, new_val: <bool as Specifier>::InOut) -> Self

Returns a copy of the bitfield with the value of lazy_refcount set to the given value.

#Panics

If the given value is out of bounds for lazy_refcount. Lazy refcounts bit. If this bit is set then lazy refcount updates can be used. This means marking the image file dirty and postponing refcount metadata updates.

pub fn with_lazy_refcount_checked( self, new_val: <bool as Specifier>::InOut, ) -> Result<Self, OutOfBounds>

Returns a copy of the bitfield with the value of lazy_refcount set to the given value.

#Errors

If the given value is out of bounds for lazy_refcount. Lazy refcounts bit. If this bit is set then lazy refcount updates can be used. This means marking the image file dirty and postponing refcount metadata updates.

pub fn set_lazy_refcount(&mut self, new_val: <bool as Specifier>::InOut)

Sets the value of lazy_refcount to the given value.

#Panics

If the given value is out of bounds for lazy_refcount. Lazy refcounts bit. If this bit is set then lazy refcount updates can be used. This means marking the image file dirty and postponing refcount metadata updates.

pub fn set_lazy_refcount_checked( &mut self, new_val: <bool as Specifier>::InOut, ) -> Result<(), OutOfBounds>

Sets the value of lazy_refcount to the given value.

#Errors

If the given value is out of bounds for lazy_refcount. Lazy refcounts bit. If this bit is set then lazy refcount updates can be used. This means marking the image file dirty and postponing refcount metadata updates.

Trait Implementations

impl BinRead for CompatibleFeatures

type Args = ()

The type of arguments needed to be supplied in order to read this type, usually a tuple.

fn read_options<R: Read + Seek>( __binread_generated_var_reader: &mut R, __binread_generated_var_options: &ReadOptions, __binread_generated_var_arguments: Self::Args, ) -> BinResult<Self>

Read the type from the reader

fn read<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + Seek,

Read the type from the reader while assuming no arguments have been passed

fn read_args<R>(reader: &mut R, args: Self::Args) -> Result<Self, Error>

where R: Read + Seek,

Read the type from the reader using the specified arguments

fn after_parse<R>( &mut self, _: &mut R, _: &ReadOptions, _: Self::Args, ) -> Result<(), Error>

where R: Read + Seek,

fn args_default() -> Option<Self::Args>

The default arguments to be used when using the read shortcut method. Override this for any type that optionally requries arguments

impl CheckFillsUnalignedBits for CompatibleFeatures
