Function core::intrinsics::float_to_int_unchecked[][src]

pub unsafe extern "rust-intrinsic" fn float_to_int_unchecked<Float: Copy, Int: Copy>(
    value: Float
) -> Int
🔬 This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
