Implementations

impl Quirc

pub fn identify<'a>( &'a mut self, width: usize, height: usize, image: &[u8], ) -> CodeIter<'a>

These functions are used to process images for QR-code recognition. The locations and content of each code may be obtained using accessor functions described below.

impl Quirc

pub fn new() -> Self

Construct a new QR-code recognizer.

pub fn resize(&mut self, width: usize, height: usize)

Resize the QR-code recognizer. The size of an image must be specified before codes can be analyzed.

This function returns 0 on success, or -1 if sufficient memory could not be allocated.

pub fn num_regions(&self) -> usize

pub fn num_capstones(&self) -> usize

pub fn count(&self) -> usize

Return the number of QR-codes identified in the last processed image.

pub fn reset(&mut self)

Resets all internal state.

Trait Implementations

impl Clone for Quirc

fn clone(&self) -> Quirc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Quirc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Quirc

fn default() -> Self

Returns the “default value” for a type.
