Enum qrcode::types::EcLevel

pub enum EcLevel {
    L,
    M,
    Q,
    H,
}

The error correction level. It allows the original information be recovered even if parts of the code is damaged.

Variants

L

Low error correction. Allows up to 7% of wrong blocks.

M

Medium error correction (default). Allows up to 15% of wrong blocks.

Q

"Quartile" error correction. Allows up to 25% of wrong blocks.

H

High error correction. Allows up to 30% of wrong blocks.
