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

#[repr(transparent)]
pub struct Buffer(pub [u8; 16]);

---

A Buffer represents a single contiguous memory segment

Implementations

impl Buffer

pub fn new(offset: i64, length: i64) -> Self

pub fn offset(&self) -> i64

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

pub fn set_offset(&mut self, x: i64)

pub fn length(&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.

pub fn set_length(&mut self, x: i64)

Trait Implementations

impl Clone for Buffer

fn clone(&self) -> Buffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Buffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Follow<'a> for Buffer

type Inner = &'a Buffer

fn follow(buf: &'a [u8], loc: usize) -> Self::Inner

impl<'a> Follow<'a> for &'a Buffer

type Inner = &'a Buffer

fn follow(buf: &'a [u8], loc: usize) -> Self::Inner

impl PartialEq<Buffer> for Buffer

fn eq(&self, other: &Buffer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Buffer) -> bool

This method tests for !=.

impl<'b> Push for Buffer

type Output = Buffer

fn push(&self, dst: &mut [u8], _rest: &[u8])

fn size() -> usize

fn alignment() -> PushAlignment

impl<'b> Push for &'b Buffer

type Output = Buffer

fn push(&self, dst: &mut [u8], _rest: &[u8])

fn size() -> usize

impl<'a> Verifiable for Buffer

fn run_verifier(
    v: &mut Verifier<'_, '_>,
    pos: usize
) -> Result<(), InvalidFlatbuffer>

Runs the verifier for this type, assuming its at position pos in the verifier’s buffer. Should not need to be called directly.
