QR code generation helper for Bitcoin URIs

Implementations§

Source§

impl QrCodeHelper

Source

pub fn recommended_error_correction() -> &'static str

Get the recommended QR code error correction level

BIP 21 recommends using Medium (M) level

Source

pub fn estimate_qr_version(uri: &BitcoinUri) -> u8

Estimate QR code size needed for a URI

Returns the recommended QR code version (1-40)

Source

pub fn is_qr_friendly(uri: &BitcoinUri) -> bool

Check if a URI is suitable for QR code

Returns true if the URI can fit in a reasonable QR code size
