Struct PivotByLineContext

pub struct PivotByLineContext { /* private fields */ }

Context used by methods requiring pivot. Loads cover text line by line, uses pivot and does not preserve original whitespace. It also exposes the word iterator for purpose of peeking and/or traversing.

Implementations

impl PivotByLineContext

pub fn new(cover_text: &str, pivot: usize) -> Self

pub fn get_pivot(&self) -> usize

pub fn peek_word(&mut self) -> Option<String>

pub fn next_word(&mut self) -> Option<String>

Trait Implementations

impl Context for PivotByLineContext

fn get_current_text_mut(&mut self) -> Result<&mut String, ContextError>

Gets currently loaded cover text fragment mutably.

fn get_current_text(&self) -> Result<&String, ContextError>

Gets currently loaded cover text fragment as read-only.

fn load_text(&mut self) -> Result<&str, ContextError>

Loads next cover text fragment.

impl Encoder<PivotByLineContext> for ELUVMethod

fn partial_encode( &self, context: &mut PivotByLineContext, data: &mut dyn Iterator<Item = Bit>, ) -> Result<EncoderResult, Box<dyn Error>>

Encodes bits provided by data iterator. Every Encoder has Context which exposes access to cover text. See Context for more info.

fn encode( &self, context: &mut E, data: &mut dyn Iterator<Item = Bit>, progress_channel: Option<&Sender<ProgressStatus>>, ) -> Result<String, Box<dyn Error>>

impl Encoder<PivotByLineContext> for ExtendedLineMethod

fn partial_encode( &self, context: &mut PivotByLineContext, data: &mut dyn Iterator<Item = Bit>, ) -> Result<EncoderResult, Box<dyn Error>>

Encodes bits provided by data iterator. Every Encoder has Context which exposes access to cover text. See Context for more info.

fn encode( &self, context: &mut E, data: &mut dyn Iterator<Item = Bit>, progress_channel: Option<&Sender<ProgressStatus>>, ) -> Result<String, Box<dyn Error>>

impl Encoder<PivotByLineContext> for LineExtendMethod

fn partial_encode( &self, context: &mut PivotByLineContext, data: &mut dyn Iterator<Item = Bit>, ) -> Result<EncoderResult, Box<dyn Error>>

Encodes bits provided by data iterator. Every Encoder has Context which exposes access to cover text. See Context for more info.

fn encode( &self, context: &mut E, data: &mut dyn Iterator<Item = Bit>, progress_channel: Option<&Sender<ProgressStatus>>, ) -> Result<String, Box<dyn Error>>
