Enum MicroVersion 

pub enum MicroVersion {
    M1,
    M2,
    M3,
    M4,
}

A Micro QR symbol version, M1–M4. The module grid is 11 + 2 * (n - 1) on a side.

Variants

M1

11×11, numeric only, error-detection only (no correctable EC).

M2

13×13, supports EC levels L and M.

M3

15×15, supports EC levels L and M.

M4

17×17, supports EC levels L, M and Q.

Implementations

impl MicroVersion

pub fn number(self) -> u8

The version index 1–4 (M1 → 1 … M4 → 4).

pub fn from_number(n: u8) -> Option<Self>

Construct from the index 1–4.

pub fn size(self) -> usize

Side length of the (square) module grid.

pub fn from_size(size: usize) -> Option<Self>

Recover a version from the grid side length, if valid.
