Struct rqr::version::Version

pub struct Version(pub usize);

QR code version, defines the size

Methods

impl Version

pub fn new(v: usize) -> Version

Create a new version, must be in the [1..40] range.

pub fn minimal(s: &str, mode: Mode, e: ECLevel) -> Option<Version>

Calculate the minimal required version to hold the string in the given mode with the required error correction level.

pub fn capacity(&self, mode: Mode, e: ECLevel) -> usize

Return the data capacity.

pub fn size(&self) -> usize

Return the size of the QR code.

pub fn char_count_len(&self, mode: Mode) -> usize

Returns the required len of the char count bit representation.

pub fn extra_version_areas(&self) -> bool

Returns true if this version requires extra version areas.

pub fn dark_module_pos(&self) -> (usize, usize)

Returns the position of the dark module.

pub fn index(&self) -> usize

Return the version value - 1, suitable for indexing.
