Implementations§

source§

impl Align

source

pub const ONE: Align = _

source

pub const MAX: Align = _

source

pub fn from_bits(bits: u64) -> Result<Align, String>

source

pub fn from_bytes(align: u64) -> Result<Align, String>

source

pub fn bytes(self) -> u64

source

pub fn bits(self) -> u64

source

pub fn max_for_offset(offset: Size) -> Align

Computes the best alignment possible for the given offset (the largest power of two that the offset is a multiple of).

N.B., for an offset of 0, this happens to return 2^64.

source

pub fn restrict_for_offset(self, offset: Size) -> Align

Lower the alignment, if necessary, such that the given offset is aligned to it (the offset is a multiple of the alignment).
