Struct solana_rbpf::aligned_memory::AlignedMemory

pub struct AlignedMemory { /* fields omitted */ }

Provides u8 slices at a specified alignment

Implementations

impl AlignedMemory

pub fn new(max_len: usize, align: usize) -> Self

Return a new AlignedMemory type

pub fn new_with_size(len: usize, align: usize) -> Self

Return a pre-filled AlignedMemory type

pub fn new_with_data(data: &[u8], align: usize) -> Self

Return a pre-filled AlignedMemory type

pub fn len(&self) -> usize

Get the length of the data

pub fn is_empty(&self) -> bool

Is the memory empty

pub fn write_index(&self) -> usize

Get the current write index

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

Get an aligned slice

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

Get an aligned mutable slice

pub fn resize(&mut self, num: usize, value: u8) -> Result<()>

resize memory with value starting at the write_index

Trait Implementations

impl Clone for AlignedMemory

fn clone(&self) -> AlignedMemory

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AlignedMemory

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

Formats the value using the given formatter.

impl PartialEq<AlignedMemory> for AlignedMemory

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

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

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

This method tests for !=.

impl Write for AlignedMemory

fn write(&mut self, buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adapter for this instance of Write.
