Enum OutputDuplicationError 

pub enum OutputDuplicationError {
    NoOutput,
    DeviceError(Error),
}

Available on Windows only.

Errors that can occur during output duplication initialization.

Variants

NoOutput

No suitable output display was found.

This occurs when no displays are connected, all displays are disabled, or the graphics driver doesn’t support Desktop Duplication.

Recovery: Ensure a display is connected and graphics drivers support Desktop Duplication.

DeviceError(Error)

Failed to create the D3D11 device or duplicate the output.

This can occur due to graphics driver issues, insufficient system resources, or incompatible graphics hardware.

Recovery: Check graphics driver installation and system resources.
