This name is emitted by the generator and already known to not contain
any null-characters: replace the runtime iteration+comparison (hidden
behind `from_bytes_with_nul`) and `.expect()` panic with an `unsafe`
"cast" through `from_bytes_with_nul_unchecked`, just like the
function-pointer loaders.
On platforms like Android strings use `u8` as character-type instead of
`i8` - using the appropriate `c_char` type hides this discrepancy and
allows the examples to compile for all platforms.
* extensions: Make naming and layout consistent across all extensions
breaking change:
- some extensions were exposing `instance()` instead of `device()`
includes:
- renaming function pointer member to `fns`
- moving `name()`, `fp(`), `device()`/`instance()` functions at end of file
- adding missing `device()`/`instance()` functions
see https://github.com/MaikKlein/ash/pull/493
* debug_marker: Remove unneeded `device` from `debug_marker_set_object_name()`
* extensions: Remove unneeded `instance` and `device` struct members and functions
* extensions: renamed all `fns` fields to `fp` to match `pub fn fp()` getter
Fixes https://github.com/MaikKlein/ash/issues/354
`io::Read::read_exact` does not receive `MaybeUninit` memory and a trait
implementation can possibly read from our uninitialized vector without
`unsafe`, which is UB. As there is no proper solution to this problem
yet (see linked issue), our safest bet is to just take the perf-hit and
zero-initialize this vector.
