Struct Code 

pub struct Code(/* private fields */);

A positive errno established by one native failure or completion field.

Implementations

impl Code

pub unsafe fn last<S: Source + ?Sized>() -> Self

Retains the positive error number established by one failed native call.

Safety

A failed native call left this thread’s errno positive and unchanged.

pub const unsafe fn new(raw: i32) -> Self

Retains the positive domain established by the native producer.

Safety

raw is positive, as established by the unchanged native error field.

pub unsafe fn from_native(raw: intptr_t) -> Option<Self>

Retains the errno one native completion field reports, if any.

Safety

raw is that completion’s exact field: zero or a positive c_int.
