Struct rustler::OwnedBinary

pub struct OwnedBinary { /* fields omitted */ }

Methods

impl<'a> OwnedBinary

pub unsafe fn from_raw(inner: ErlNifBinary) -> OwnedBinary

pub fn new(size: usize) -> Option<OwnedBinary>

Allocates a new OwnedBinary with size size.

Note that the memory is not initially guaranteed to be any particular value. If an empty buffer is needed, you should manually zero it.

pub fn from_unowned(from_bin: &Binary) -> Option<OwnedBinary>

Copies a given Binary.

#[must_use]

pub fn realloc(&mut self, size: usize) -> bool

Attempts to reallocate the buffer with the new size. Returns false if the buffer cannot be reallocated.

pub fn realloc_or_copy(&mut self, size: usize)

Attempts to reallocate the buffer with the new size. If reallocation fails, it will perform a copy instead. Memory outside the range of the original buffer will not be initialized. If this needs to be empty, clear it manually.

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

pub fn as_mut_slice(&mut self) -> &'a mut [u8]

pub fn release<'b>(self, env: Env<'b>) -> Binary<'b>

Releases control of the binary to the VM. After this point the binary will be immutable.
