pub struct FnPtr {
    f: *const c_void,
    is_loaded: bool,
}

Fields

f: *const c_void

The function pointer that will be used when calling the function.

is_loaded: bool

True if the pointer points to a real function, false if points to a panic! fn.

Implementations

impl FnPtr

fn new(ptr: *const c_void) -> FnPtr

Creates a FnPtr from a load attempt.

pub fn is_loaded(&self) -> bool

Returns true if the function has been successfully loaded.

If it returns false, calling the corresponding function will fail.

fn clone(&self) -> FnPtr

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
