Implementations

impl PackedOffsetAndFlags

pub const fn new() -> Self

Returns an instance with zero initialized data.

impl PackedOffsetAndFlags

pub const fn into_bytes(self) -> [u8; 4]

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; 4]) -> Self

Converts the given bytes directly into the bitfield struct.

impl PackedOffsetAndFlags

fn offset_reduced(&self) -> <B31 as Specifier>::InOut

Returns the value of offset_reduced. this provides 2^31 bits, which when multipled by 8 (sizeof(u64)) = 16G, which is the maximum size of an append vec

fn offset_reduced_or_err( &self ) -> Result<<B31 as Specifier>::InOut, InvalidBitPattern<<B31 as Specifier>::Bytes>>

Returns the value of offset_reduced.

#Errors

If the returned value contains an invalid bit pattern for offset_reduced. this provides 2^31 bits, which when multipled by 8 (sizeof(u64)) = 16G, which is the maximum size of an append vec

fn with_offset_reduced(self, new_val: <B31 as Specifier>::InOut) -> Self

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

#Panics

If the given value is out of bounds for offset_reduced. this provides 2^31 bits, which when multipled by 8 (sizeof(u64)) = 16G, which is the maximum size of an append vec

fn with_offset_reduced_checked( self, new_val: <B31 as Specifier>::InOut ) -> Result<Self, OutOfBounds>

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

#Errors

If the given value is out of bounds for offset_reduced. this provides 2^31 bits, which when multipled by 8 (sizeof(u64)) = 16G, which is the maximum size of an append vec

fn set_offset_reduced(&mut self, new_val: <B31 as Specifier>::InOut)

Sets the value of offset_reduced to the given value.

#Panics

If the given value is out of bounds for offset_reduced. this provides 2^31 bits, which when multipled by 8 (sizeof(u64)) = 16G, which is the maximum size of an append vec

fn set_offset_reduced_checked( &mut self, new_val: <B31 as Specifier>::InOut ) -> Result<(), OutOfBounds>

Sets the value of offset_reduced to the given value.

#Errors

If the given value is out of bounds for offset_reduced. this provides 2^31 bits, which when multipled by 8 (sizeof(u64)) = 16G, which is the maximum size of an append vec

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

Returns the value of is_zero_lamport. use 1 bit to specify that the entry is zero lamport

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

Returns the value of is_zero_lamport.

#Errors

If the returned value contains an invalid bit pattern for is_zero_lamport. use 1 bit to specify that the entry is zero lamport

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

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

#Panics

If the given value is out of bounds for is_zero_lamport. use 1 bit to specify that the entry is zero lamport

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

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

#Errors

If the given value is out of bounds for is_zero_lamport. use 1 bit to specify that the entry is zero lamport

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

Sets the value of is_zero_lamport to the given value.

#Panics

If the given value is out of bounds for is_zero_lamport. use 1 bit to specify that the entry is zero lamport

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

Sets the value of is_zero_lamport to the given value.

#Errors

If the given value is out of bounds for is_zero_lamport. use 1 bit to specify that the entry is zero lamport

Trait Implementations

impl CheckFillsUnalignedBits for PackedOffsetAndFlags

type CheckType = [(); 1]

impl Clone for PackedOffsetAndFlags

fn clone(&self) -> PackedOffsetAndFlags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackedOffsetAndFlags

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

Formats the value using the given formatter.

impl Default for PackedOffsetAndFlags

fn default() -> PackedOffsetAndFlags

Returns the “default value” for a type.

impl PartialEq<PackedOffsetAndFlags> for PackedOffsetAndFlags

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