Struct CSTL_Alloc

#[repr(C)]
pub struct CSTL_Alloc {
    pub opaque: *mut c_void,
    pub aligned_alloc: Option<unsafe extern "C" fn(opaque: *mut c_void, size: usize, alignment: usize) -> *mut c_void>,
    pub aligned_free: Option<unsafe extern "C" fn(opaque: *mut c_void, memory: *mut c_void, size: usize, alignment: usize)>,
}

Opaque memory allocator interface.

The caller is responsible for making sure an allocator owns and is compatible for freeing memory of a given container.

aligned_alloc and aligned_free must not be null, while allocator can be used to pass any opaque data (if any) directly to the bound functions.

A strict alignment requirement may be imposed by allocated types.

Fields

opaque: *mut c_void

Pointer to opaque data, passed to bound memory allocation functions.

aligned_alloc: Option<unsafe extern "C" fn(opaque: *mut c_void, size: usize, alignment: usize) -> *mut c_void>

Must return a memory block of at least size bytes that is at least as aligned as alignment

aligned_free: Option<unsafe extern "C" fn(opaque: *mut c_void, memory: *mut c_void, size: usize, alignment: usize)>

Must be able to free previously allocated memory.

The caller is responsible for allocator compatibility.
