Struct SharedAlignedBuffer

pub struct SharedAlignedBuffer { /* private fields */ }

Shared aligned buffer for executor purposes.

See OwnedAlignedBuffer for a version that can be mutated.

Data is aligned to 16 bytes (128 bits), which is the largest alignment required by primitive types and by extension any type that implements TrivialType/IoType.

NOTE: Counter for number of shared instances is u32 and will wrap around if exceeded breaking internal invariants (which is extremely unlikely, but still).

Implementations

impl SharedAlignedBuffer

pub fn empty_ref() -> &'static Self

Static reference to an empty buffer

pub fn from_bytes(bytes: &[u8]) -> Self

Create a new instance from provided bytes.

Panics

If bytes.len() doesn’t fit into u32

pub fn into_owned(self) -> OwnedAlignedBuffer

Convert into owned buffer.

If this is the last shared instance, then allocation will be reused, otherwise new allocation will be created.

Returns None if there exit other shared instances.

pub fn as_slice(&self) -> &[u8]

pub fn as_ptr(&self) -> *const u8

pub fn is_empty(&self) -> bool

pub fn len(&self) -> u32
