Struct Allocator 

#[repr(C)]
pub struct Allocator {
    pub ctx: *mut c_void,
    pub vtable: *const AllocatorVtable,
}

Custom memory allocator.

For functions that take an allocator pointer, a NULL pointer indicates that the default allocator should be used. The default allocator will be libc malloc/free if we’re linking to libc. If libc isn’t linked, a custom allocator is used (currently Zig’s SMP allocator).

Usage example: GhosttyAllocator allocator = { .vtable = &my_allocator_vtable, .ctx = my_allocator_state };

Fields

ctx: *mut c_void

Opaque context pointer passed to all vtable functions. This allows the allocator implementation to maintain state or reference external resources needed for memory management.

vtable: *const AllocatorVtable

Pointer to the allocator’s vtable containing function pointers for memory operations (alloc, resize, remap, free).
