Function s2n_quic::provider::tls::default::ffi::s2n_mem_set_callbacks

pub unsafe extern "C" fn s2n_mem_set_callbacks(
    mem_init_callback: Option<unsafe extern "C" fn() -> i32>,
    mem_cleanup_callback: Option<unsafe extern "C" fn() -> i32>,
    mem_malloc_callback: Option<unsafe extern "C" fn(_: *mut *mut c_void, _: u32, _: *mut u32) -> i32>,
    mem_free_callback: Option<unsafe extern "C" fn(_: *mut c_void, _: u32) -> i32>,
) -> i32

Allows the caller to override s2n-tls’s internal memory handling functions.

@warning This function must be called before s2n_init().
