Enum dokan::OperationError

[−] Show declaration

pub enum OperationError {
    NtStatus(NTSTATUS),
    Win32(DWORD),
}

[−] Expand description

The error type for callbacks of FileSystemHandler.

This enum represents either an NTSTATUS code or a Win32 error code. Dokan only accepts NTSTATUS codes, so if a Win32 error code is present, it will be automatically converted to the corresponding NTSTATUS value.

Note that although STATUS_SUCCESS and ERROR_SUCCESS are used to indicate successes in the Windows world, they are not expected to appear in this enum and will be converted to STATUS_INTERNAL_ERROR if detected. This error type is always used along with Results in this crate and Ok should be returned to indicate successes instead.
