Struct std::os::windows::io::NullHandleError

source · [−]

pub struct NullHandleError(_);

🔬 This is a nightly-only experimental API. (io_safety #87074)

Available on Windows only.

Expand description

This is the error type used by HandleOrNull when attempting to convert into a handle, to indicate that the value is null.
