Type Alias UnitCompletion 

pub type UnitCompletion = SyncCompletion<()>;

Unit completion - for operations that return success/error without a value

Aliased Type

pub struct UnitCompletion { /* private fields */ }

Implementations

impl UnitCompletion

pub extern "C" fn callback( context: *mut c_void, success: bool, msg: *const i8, )

C callback for operations that return (context, success, error_msg)

This can be used directly as an FFI callback function.

The body is wrapped in catch_user_panic so that a mutex-poison panic (or any other unexpected panic) does not unwind across the extern "C" boundary, which would be undefined behaviour.
