[−][src]Struct rqr::version::Version
QR code version, defines the size
Methods
impl Version
[src]
pub fn new(v: usize) -> Version
[src]
Create a new version, must be in the [1..40] range.
pub fn minimal(s: &str, mode: Mode, e: ECLevel) -> Option<Version>
[src]
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
[src]
Return the data capacity.
pub fn size(&self) -> usize
[src]
Return the size of the QR code.
pub fn char_count_len(&self, mode: Mode) -> usize
[src]
Returns the required len of the char count bit representation.
pub fn extra_version_areas(&self) -> bool
[src]
Returns true if this version requires extra version areas.
pub fn dark_module_pos(&self) -> (usize, usize)
[src]
Returns the position of the dark module.
pub fn index(&self) -> usize
[src]
Return the version value - 1, suitable for indexing.
