Struct EncodingModes 

pub struct EncodingModes { /* private fields */ }

Set of QR data modes used by an encoded bit stream.

This records which payload modes were emitted, without retaining input bytes or every segment boundary. Use iter when call sites need the modes in a stable QR mode order.

Implementations

impl EncodingModes

pub const fn empty() -> Self

Creates an empty mode set.

pub const fn from_mode(mode: Mode) -> Self

Creates a mode set containing one mode.

pub const fn contains(self, mode: Mode) -> bool

Returns true when mode was used by the encoded bit stream.

pub const fn is_empty(self) -> bool

Returns true when no data modes have been recorded.

pub const fn len(self) -> usize

Number of distinct data modes recorded.

pub const fn iter(self) -> EncodingModesIter

Returns an iterator over the recorded modes in stable QR mode order: Numeric, Alphanumeric, Byte, Kanji.
