Provided Methods

fn malloc_align(&self, size: u64) -> Align

Returns the alignment that malloc would guarantee for requests of the given size.

fn emulate_allocator( &mut self, default: impl FnOnce(&mut MiriInterpCx<'tcx>) -> InterpResult<'tcx>, ) -> InterpResult<'tcx, EmulateItemResult>

Emulates calling the internal _rust* allocator functions

fn malloc(&mut self, size: u64, zero_init: bool) -> InterpResult<'tcx, Pointer>

fn posix_memalign( &mut self, memptr: &OpTy<'tcx>, align: &OpTy<'tcx>, size: &OpTy<'tcx>, ) -> InterpResult<'tcx, Scalar>

fn free(&mut self, ptr: Pointer) -> InterpResult<'tcx>

fn realloc( &mut self, old_ptr: Pointer, new_size: u64, ) -> InterpResult<'tcx, Pointer>

fn aligned_alloc( &mut self, align: &OpTy<'tcx>, size: &OpTy<'tcx>, ) -> InterpResult<'tcx, Pointer>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
