pub(crate) pow2: u8,
}
Expand description
Alignment of a type in bytes (always a power of two).

Implementations§
source§impl Align
impl Align
pub const ONE: Align = _
pub const MAX: Align = _
pub fn from_bits(bits: u64) -> Result<Align, AlignFromBytesError>
pub fn from_bytes(align: u64) -> Result<Align, AlignFromBytesError>
pub fn bytes(self) -> u64
pub fn bits(self) -> u64
sourcepub fn max_for_offset(offset: Size) -> Align
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
.
sourcepub fn restrict_for_offset(self, offset: Size) -> Align
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).

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
