Struct fast_qr::qr::QRBuilder

pub struct QRBuilder { /* private fields */ }

Builder struct, makes it easier to create a QRCode.

Example

use fast_qr::QRBuilder;
use fast_qr::{Mask, ECL, Version};

// Creates a `QRCode` with a forced `version`, `ecl` and/or `mask`
let input = String::from("Hello World!");
let qr = QRBuilder::new(input)
    // .version(Version::V05)
    // .ecl(ECL::H)
    // .mask(Mask::Checkerboard)
    .build();

Implementations

impl QRBuilder

pub fn new<I: Into<Vec<u8>>>(input: I) -> QRBuilder

Creates an instance of QRBuilder with default parameters

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

Forces the Mode

pub fn ecl(&mut self, ecl: ECL) -> &mut Self

Forces the Encoding Level

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

Forces the version

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

Forces the mask, should very rarely be used

pub fn build(&self) -> Result<QRCode, QRCodeError>

Computes a QRCode with given parameters

Errors

• QRCodeError::EncodedData if input is too large to be encoded. See an online table for more info.
• QRCodeError::SpecifiedVersion if specified version is too small to contain data
