Expand description

Trait that has methods to convert raw data from the webcam to a proper raw image.

Required Associated Constants§

Source

const FORMATS: &'static [FrameFormat]

Required Associated Types§

Source

type Output: Pixel<Subpixel = u8>

Required Methods§

Source

fn write_output( fcc: FrameFormat, resolution: Resolution, data: &[u8], ) -> Result<Vec<u8>, NokhwaError>

Allocates and returns a Vec

§Errors

If the data is malformed, or the source FrameFormat is incompatible, this will error.

Source

fn write_output_buffer( fcc: FrameFormat, resolution: Resolution, data: &[u8], dest: &mut [u8], ) -> Result<(), NokhwaError>

Writes to a user provided buffer.

§Errors

If the data is malformed, the source FrameFormat is incompatible, or the user-alloted buffer is not large enough, this will error.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
