Struct Encoder 

pub struct Encoder { /* private fields */ }

Available on crate feature micro-qr only.

Configures and encodes Micro QR Code symbols.

Implementations

impl MicroEncoder

pub const fn new(error_correction: MicroErrorCorrection) -> Self

Creates an encoder with automatic mask selection and all Micro QR Code versions.

pub const fn version(self, version: MicroVersion) -> Self

Selects one exact Micro QR Code version.

pub const fn version_range(self, versions: RangeInclusive<MicroVersion>) -> Self

Selects the inclusive Micro QR Code version range considered during encoding.

pub const fn mask(self, mask: MicroMask) -> Self

Forces an exact mask instead of selecting one automatically.

pub const fn boost_error_correction(self, boost: bool) -> Self

Enables or disables upgrading the error correction level when the selected version has room.

pub fn encode_bytes( &self, data: impl AsRef<[u8]>, ) -> Result<Symbol, EncodeError>

Encodes raw bytes with globally optimized modes supported by each candidate version.

pub fn encode_text(&self, text: impl AsRef<str>) -> Result<Symbol, EncodeError>

Encodes text with globally optimized modes supported by each candidate version.

pub fn encode_to_qr_text<T: ToQRText + ?Sized>( &self, value: &T, ) -> Result<Symbol, EncodeError>

Encodes a value after converting it to its QR Code text representation.

pub fn encode_segments( &self, segments: &[Segment], ) -> Result<Symbol, EncodeError>

Encodes explicit segments without changing their boundaries.

The segments are written as given, so avoid Byte segments holding E0 to EB in a symbol with Kanji segments, because readers could take them for Shift JIS lead bytes. An empty Numeric segment is left out, because Micro QR Code writes it with the same bits as the terminator.

Trait Implementations

impl Clone for MicroEncoder

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MicroEncoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
