Struct AlignedPage

#[repr(C, align(4096))]
pub struct AlignedPage(/* private fields */);

A wrapper data structure with 4096 bytes alignment, which is the most common alignment for direct I/O operations.

Implementations

impl AlignedPage

pub const SIZE: usize = 4_096usize

4096 is as a relatively safe size due to sector size on SSDs commonly being 512 or 4096 bytes

pub fn as_uninit_slice_mut(value: &mut [Self]) -> &mut [MaybeUninit<Self>]

Convert an exclusive slice to an uninitialized version

pub fn slice_to_repr(value: &[Self]) -> &[[u8; 4096]]

Convenient conversion from slice to underlying representation for efficiency purposes

pub fn uninit_slice_to_repr( value: &[MaybeUninit<Self>], ) -> &[MaybeUninit<[u8; 4096]>]

Convenient conversion from slice to underlying representation for efficiency purposes

pub fn try_slice_from_repr(value: &[[u8; 4096]]) -> Option<&[Self]>

Convenient conversion from a slice of underlying representation for efficiency purposes.

Returns None if not correctly aligned.

pub fn try_uninit_slice_from_repr( value: &[MaybeUninit<[u8; 4096]>], ) -> Option<&[MaybeUninit<Self>]>

Convenient conversion from a slice of underlying representation for efficiency purposes.

Returns None if not correctly aligned.

pub fn slice_mut_to_repr(slice: &mut [Self]) -> &mut [[u8; 4096]]

Convenient conversion from mutable slice to underlying representation for efficiency purposes

pub fn uninit_slice_mut_to_repr( slice: &mut [MaybeUninit<Self>], ) -> &mut [MaybeUninit<[u8; 4096]>]

Convenient conversion from mutable slice to underlying representation for efficiency purposes

pub fn try_slice_mut_from_repr(value: &mut [[u8; 4096]]) -> Option<&mut [Self]>

Convenient conversion from a slice of underlying representation for efficiency purposes.

Returns None if not correctly aligned.

pub fn try_uninit_slice_mut_from_repr( value: &mut [MaybeUninit<[u8; 4096]>], ) -> Option<&mut [MaybeUninit<Self>]>

Convenient conversion from a slice of underlying representation for efficiency purposes.

Returns None if not correctly aligned.
