Struct pyembed::PythonMemoryAllocator

pub struct PythonMemoryAllocator { /* private fields */ }

Represents a custom memory allocator that can be registered with Python.

Implementations

impl PythonMemoryAllocator

pub fn from_backend(backend: MemoryAllocatorBackend) -> Option<Self>

Construct an instance from a MemoryAllocatorBackend.

Returns None if the backend shouldn’t be defined.

pub fn jemalloc() -> Self

pub fn mimalloc() -> Self

pub fn rust() -> Self

Construct a new instance using Rust’s global allocator.

pub fn snmalloc() -> Self

pub fn backend(&self) -> MemoryAllocatorBackend

Obtain the backend used for this instance.

pub fn set_allocator(&self, domain: PyMemAllocatorDomain)

Set this allocator to be the allocator for a certain “domain” in a Python interpreter.

This should be called before Py_Initialize*().

pub fn set_arena_allocator(&self)

Set the arena allocator used by the pymalloc allocator.

This only has an effect if the pymalloc allocator is registered to the mem or object allocator domains.
