Enum ErrorCorrectionLevel

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

Represents the error correction levels for QR codes

Variants

• L: Lowest error correction (approximately 7% of codewords can be restored)
• M: Medium error correction (approximately 15% of codewords can be restored)
• Q: Quartile error correction (approximately 25% of codewords can be restored)
• H: Highest error correction (approximately 30% of codewords can be restored)

Methods

Provides methods to retrieve various parameters specific to each error correction level:

• get_format_bits: Get the format bits for the error correction level
• get_alpha_numeric_version_size: Get max capacity for alphanumeric encoding
• get_numeric_version_size: Get max capacity for numeric encoding
• get_byte_version_size: Get max capacity for byte encoding
• get_num_codewords: Get number of codewords

Example

let max_numeric_size = ErrorCorrectionLevel::M.get_numeric_version_size(1); 

Variants

L

M

Medium error correction (approximately 15% of codewords can be restored)

Q

Quartile error correction (approximately 25% of codewords can be restored

H

Highest error correction (approximately 30% of codewords can be restored)

Trait Implementations

impl Debug for ErrorCorrectionLevel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ErrorCorrectionLevel

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
