BrCode functions context relatedpub fn is_pix(&self) -> bool determines if BrCode is a PIX transaction.pub fn get_transaction_id(&self) -> Option<String> gets transaction_id value (field 5 of item 65).pub fn get_alias(&self) -> Option<Vec<String>> gets all possible values for PIX aliases. Usually only field 1 of item 26 is valid. Checks if the alias if of type "BR.GOV.BCB.PIX".pub fn get_message(&self) -> Option<Vec<String>> gets all possible massages for PIX aliases. Usually only field 2 of item 26 is valid. Checks if the alias if of type "BR.GOV.BCB.PIX".BrCode functions QrCode generation related:to_svg_string(&self, ecc: QrCodeEcc, size: usize) -> String generates a SVG xml in a String.to_svg_standard_string(&self) -> String generates a SVG xml in a String with QrCodeEcc::Low and size = 1024.to_vec_u8(&self, ecc: QrCodeEcc, size: usize) -> Vec<u8> generates a PNG formatted in Vec<u8>.to_svg_file(&self, file_path: &str, ecc: QrCodeEcc, size: usize) creates a QR Code in format .svg located at file path file_path.to_standard_svg_file(&self, file_path: &str) creates a QR Code in format .svg located at file path file_path with QrCodeEcc::Low and size = 1024.to_png_file(&self, file_path: &str, ecc: QrCodeEcc, size: usize) creates a QR Code in format .png located at file path file_path.
file_path examples are tests/data/file_output.png and tests/data/file_output.svg from the project root. If directory doesn't exist an error will be thrown.
QrCodeEcc is the error correction level in a QR Code symbol and size is the image size.
QrCodeEcc::Low The QR Code can tolerate about 7% erroneous codewords.QrCodeEcc::Medium The QR Code can tolerate about 15% erroneous codewords.QrCodeEcc::Quartile The QR Code can tolerate about 25% erroneous codewords.QrCodeEcc::High The QR Code can tolerate about 30% erroneous codewords.from_str in benches/parse.rs
