Struct ConstVersion 

pub struct ConstVersion<const N: i16>;

A compile-time checked normal QR version.

N must be in the normal QR version range 1..=40. The range is checked when ConstVersion::new or ConstVersion::VALUE is evaluated, so an invalid fixed-version path fails at compile time instead of reaching the encoder.

use qrcode_core::{ConstVersion, Version};

const V5: Version = ConstVersion::<5>::VALUE;
assert_eq!(V5, Version::Normal(5));

use qrcode_core::ConstVersion;

const INVALID: qrcode_core::Version = ConstVersion::<41>::VALUE;

Implementations
