Implementations

impl EntryCommands

pub unsafe fn load(f: impl FnMut(&CStr) -> *const c_void) -> EntryCommands

Load all function pointers from the given loader callback.

Load all function pointers from the given loader callback.

Safety

The loader must return valid function pointers compatible with each command’s signature, or null for unavailable commands.

Trait Implementations

impl Default for EntryCommands

fn default() -> EntryCommands

Returns the “default value” for a type.
