Struct Buffer 

pub struct Buffer { /* private fields */ }

A heap byte buffer guaranteed to be 8-byte aligned.

The largest element we store is 8 bytes (f64/i64), so backing the buffer with a Vec<u64> guarantees the start address satisfies the alignment of any DType. That in turn lets Tensor hand out typed slices (&[f32], …) by reinterpreting the bytes without a copy and without risking an unaligned read.

Storing the words (rather than a raw Vec<u8>) also keeps Drop sound: the allocation is always freed with the same Vec<u64> layout it was created with.

Implementations

impl Buffer

pub fn zeroed(len: usize) -> Buffer

A zero-initialised buffer of len bytes.

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

Copy bytes into a fresh aligned buffer.

pub fn len(&self) -> usize

Length in valid bytes.

pub fn is_empty(&self) -> bool

Whether the buffer holds zero bytes.

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

The valid bytes as a shared slice. The pointer is 8-byte aligned.

pub fn as_mut_bytes(&mut self) -> &mut [u8]

The valid bytes as a mutable slice. The pointer is 8-byte aligned.

Trait Implementations
