Struct arrow::ipc::gen::Schema::Buffer

#[repr(C, align(8))]pub struct Buffer { /* fields omitted */ }

---

A Buffer represents a single contiguous memory segment

Implementations

impl Buffer

pub fn new<'a>(_offset: i64, _length: i64) -> Self

pub fn offset<'a>(&'a self) -> i64

The relative offset into the shared memory page where the bytes for this buffer starts

pub fn length<'a>(&'a self) -> i64

The absolute length (in bytes) of the memory buffer. The memory is found from offset (inclusive) to offset + length (non-inclusive). When building messages using the encapsulated IPC message, padding bytes may be written after a buffer, but such padding bytes do not need to be accounted for in the size here.

Trait Implementations

impl Clone for Buffer

fn clone(&self) -> Buffer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
