Enum EcLevel 

pub enum EcLevel {
    L = 0,
    M = 1,
    Q = 2,
    H = 3,
}

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

Variants

L = 0

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

M = 1

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

Q = 2

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

H = 3

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

assert!(EcLevel::from_str("X").is_err());

type Err = EnumParseError

The associated error which can be returned from parsing.

impl Ord for EcLevel

fn cmp(&self, other: &EcLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for EcLevel

fn eq(&self, other: &EcLevel) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for EcLevel

fn partial_cmp(&self, other: &EcLevel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool
