Enum cglue::result::CResult

source ·
#[repr(C)]
pub enum CResult<T, E> { Ok(T), Err(E), }
Expand description

FFI safe result.

This type is not meant for general use, but rather as a last-resort conversion for type wrapping.

Typical workflow would include temporarily converting into/from CResult.

But preferred way to pass results efficiently would be to implement IntError trait on the E type.
