Fields

bytes: [u8; 8]

Implementations

impl PackedStorage

pub const fn new() -> Self

Returns an instance with zero initialized data.

impl PackedStorage

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 PackedStorage

fn capacity_when_created_pow2(&self) -> <B8 as Specifier>::InOut

Returns the value of capacity_when_created_pow2.

fn capacity_when_created_pow2_or_err( &self ) -> Result<<B8 as Specifier>::InOut, InvalidBitPattern<<B8 as Specifier>::Bytes>>

Returns the value of capacity_when_created_pow2.

#Errors

If the returned value contains an invalid bit pattern for capacity_when_created_pow2.

fn with_capacity_when_created_pow2( self, new_val: <B8 as Specifier>::InOut ) -> Self

Returns a copy of the bitfield with the value of capacity_when_created_pow2 set to the given value.

#Panics

If the given value is out of bounds for capacity_when_created_pow2.

fn with_capacity_when_created_pow2_checked( self, new_val: <B8 as Specifier>::InOut ) -> Result<Self, OutOfBounds>

Returns a copy of the bitfield with the value of capacity_when_created_pow2 set to the given value.

#Errors

If the given value is out of bounds for capacity_when_created_pow2.

fn set_capacity_when_created_pow2(&mut self, new_val: <B8 as Specifier>::InOut)

Sets the value of capacity_when_created_pow2 to the given value.

#Panics

If the given value is out of bounds for capacity_when_created_pow2.

fn set_capacity_when_created_pow2_checked( &mut self, new_val: <B8 as Specifier>::InOut ) -> Result<(), OutOfBounds>

Sets the value of capacity_when_created_pow2 to the given value.

#Errors

If the given value is out of bounds for capacity_when_created_pow2.

fn offset(&self) -> <B56 as Specifier>::InOut

Returns the value of offset.

fn offset_or_err( &self ) -> Result<<B56 as Specifier>::InOut, InvalidBitPattern<<B56 as Specifier>::Bytes>>

Returns the value of offset.

#Errors

If the returned value contains an invalid bit pattern for offset.

fn with_offset(self, new_val: <B56 as Specifier>::InOut) -> Self

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

#Panics

If the given value is out of bounds for offset.

fn with_offset_checked( self, new_val: <B56 as Specifier>::InOut ) -> Result<Self, OutOfBounds>

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

#Errors

If the given value is out of bounds for offset.

fn set_offset(&mut self, new_val: <B56 as Specifier>::InOut)

Sets the value of offset to the given value.

#Panics

If the given value is out of bounds for offset.

fn set_offset_checked( &mut self, new_val: <B56 as Specifier>::InOut ) -> Result<(), OutOfBounds>

Sets the value of offset to the given value.

#Errors

If the given value is out of bounds for offset.

Trait Implementations

impl CheckFillsUnalignedBits for PackedStorage

type CheckType = [(); 1]

impl Clone for PackedStorage

fn clone(&self) -> PackedStorage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackedStorage

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

Formats the value using the given formatter.

impl Default for PackedStorage

fn default() -> PackedStorage

Returns the “default value” for a type.

impl PartialEq<PackedStorage> for PackedStorage

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