Struct qrcode53bytes::builder::QrBuilder

pub struct QrBuilder {
    pub version: Version,
    pub mask: Option<Mask>,
    pub ecl: ECLevel,
    pub mode: Mode,
    pub matrix: Matrix,
}

Builder for a QR code.

Fields

version: Version

Version to use. If not set a minimal version will be calculated.

mask: Option<Mask>

Mask to use. If not set the optimal mask will be chosen per the QR specification.

ecl: ECLevel

Error correction level to use. If not set ECLevel::Q, which recovers 25% of data, will be used.

mode: Mode

Encoding mode to use. If not set will be inferred from input data.

matrix: Matrix

Resulting matrix.

Note that even though the matrix is not an Option it might still be invalid. This to simplify the implementation.

Implementations

impl QrBuilder

pub fn new() -> QrBuilder

Create a new builder.

pub fn version(self, v: Version) -> Self

Set version. If not set the smallest applicable version will be used.

pub fn mask(self, mask: Mask) -> Self

Set mask to use. If not set the best mask will be chosen according to the QR spec.

pub fn ecl(self, ecl: ECLevel) -> Self

Set error correction. Will default to ECLevel::Q.

pub fn mode(self, mode: Mode) -> Self

Set the mode to use, will otherwise be calculated from input.

pub fn into(self, s: &str) -> Result<Qr, Error>

Build all elements and generate a QR code.

pub fn into_qr(self) -> Result<Qr, Error>

Convert the builder into a QR code.

pub fn add_all(&mut self, s: &str) -> Result<(), Error>

Add all elements of a QR code.

pub fn add_fun_patterns(&mut self)

Add function patterns.

pub fn add_data(&mut self, s: &str) -> Result<(), Error>

Add data.

pub fn add_raw_data(&mut self, v: &BitVec<Lsb0, u8>)

Add raw data.

pub fn mask_data(&mut self)

Mask data.

pub fn mask_best(&mut self)

Mask by evaluating available masks and choose the best one.

pub fn mask_with(&mut self, mask: Mask)

Mask using a specific mask.

pub fn add_info(&mut self)

Add info.

pub fn add_format_info(&mut self)

Add format info.

fn complete(&self) -> bool

Return true if the build is complete.
