Struct Encoder 

pub struct Encoder { /* private fields */ }

Available on crate feature qr only.

Configures and encodes Model 2 QR Code symbols.

Implementations

impl QrEncoder

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

Creates an encoder with automatic mask selection and Model 2 versions 1 through 40.

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

Selects one exact Model 2 QR Code version.

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

Selects the inclusive Model 2 QR Code version range considered during encoding.

pub const fn mask(self, mask: QrMask) -> 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 const fn fnc1(self, fnc1: Option<Fnc1>) -> Self

Sets the FNC1 interpretation applied to the complete symbol.

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

Encodes raw bytes with globally optimized Numeric, Alphanumeric and Byte segments.

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

Encodes text with globally optimized character modes and ECI transitions.

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.

pub fn encode_structured_append_bytes( &self, parts: &[&[u8]], ) -> Result<Vec<Symbol>, EncodeError>

Encodes caller-selected byte parts as one Structured Append sequence.

pub fn encode_structured_append_text( &self, parts: &[&str], ) -> Result<Vec<Symbol>, EncodeError>

Encodes caller-selected text parts as one Structured Append sequence.

pub fn encode_structured_append_segments( &self, parts: &[&[Segment]], ) -> Result<Vec<Symbol>, EncodeError>

Encodes caller-selected segment parts as one Structured Append sequence.

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

Encodes bytes as one symbol or automatically splits them into at most 16 Structured Append symbols.

When the data fits one symbol, that lone symbol is returned without Structured Append metadata, because a single symbol needs no sequence header.

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

Encodes text as one symbol or automatically splits it into at most 16 Structured Append symbols.

When the text fits one symbol, that lone symbol is returned without Structured Append metadata, because a single symbol needs no sequence header.

Trait Implementations

impl Clone for QrEncoder

fn clone(&self) -> QrEncoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QrEncoder

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

Formats the value using the given formatter.
