Trait Implementations

impl Clone for ffi_closure

fn clone(&self) -> ffi_closure

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ffi_closure

Implements Debug manually since sometimes FFI_TRAMPOLINE_SIZE is too large

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ffi_closure

fn default() -> Self

Returns the “default value” for a type.
