Enum dokan::OperationError

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

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.

Variants

NtStatus(NTSTATUS)

Win32(DWORD)

impl Eq for OperationError

impl Error for OperationError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
