[−][src]Struct gmp_mpfr_sys::gmp::randfnptr_t

#[repr(C)]pub struct randfnptr_t {
    pub seed: Option<unsafe extern "C" fn(rstate: *mut randstate_t, seed: *const mpz_t)>,
    pub get: Option<unsafe extern "C" fn(rstate: *mut randstate_t, dest: *mut limb_t, nbits: c_ulong)>,

    pub iset: Option<unsafe extern "C" fn(dst: *mut randstate_t, src: *const randstate_t)>,
}

The type for the algdata field in the randstate_t struct.

Future compatibility

This type is considered internal details. These internals may change in new minor releases of this crate, though they will be kept unchanged for patch releases. Any code that makes use of these internals should list the dependency as version = "~1.2" inside Cargo.toml, not version = "1.2".

Fields

seed: Option<unsafe extern "C" fn(rstate: *mut randstate_t, seed: *const mpz_t)>

Internal implementation detail: pointer to function.

Planned change

In the next minor version of the crate (version 1.3), the type of this field will be changed to unsafe extern "C" fn(rstate: *mut randstate_t, seed: *const mpz_t), that is it will no longer be an Option.

get: Option<unsafe extern "C" fn(rstate: *mut randstate_t, dest: *mut limb_t, nbits: c_ulong)>

Internal implementation detail: pointer to function.
