}
Expand description
Size of a type in bytes.
Fields
raw: u64
Implementations
sourceimpl Size
impl Size
pub const ZERO: Size = Size { raw: 0 }
sourcepub fn from_bits(bits: impl TryInto<u64>) -> Size
pub fn from_bits(bits: impl TryInto<u64>) -> Size
Rounds bits
up to the next-higher byte boundary, if bits
is
not a multiple of 8.
pub fn from_bytes(bytes: impl TryInto<u64>) -> Size
pub fn bytes(self) -> u64
pub fn bytes_usize(self) -> usize
pub fn bits(self) -> u64
pub fn bits_usize(self) -> usize
pub fn align_to(self, align: Align) -> Size
pub fn is_aligned(self, align: Align) -> bool
pub fn checked_add<C: HasDataLayout>(self, offset: Size, cx: &C) -> Option<Size>
pub fn checked_mul<C: HasDataLayout>(self, count: u64, cx: &C) -> Option<Size>
sourcepub fn sign_extend(self, value: u128) -> u128
pub fn sign_extend(self, value: u128) -> u128
Truncates value
to self
bits and then sign-extends it to 128 bits
(i.e., if it is negative, fill with 1’s on the left).
pub fn signed_int_min(&self) -> i128
pub fn signed_int_max(&self) -> i128
pub fn unsigned_int_max(&self) -> u128

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.
