Enum ErrorCorrectionLevel 

pub enum ErrorCorrectionLevel {
    Low,
    Medium,
    Quartile,
    High,
}

二维码容错级别 — 对齐 PHP Endroid\QrCode\ErrorCorrectionLevel

容错级别越高，二维码能容忍的损坏面积越大，但数据密度越低。

Variants

Low

低容错 — 允许 7% 损坏

Medium

中等容错（默认）— 允许 15% 损坏

Quartile

四分位容错 — 允许 25% 损坏

High

高容错 — 允许 30% 损坏
