Trait ptero::encoder::Encoder

pub trait Encoder<E>: Capacity where
    E: Context, {
    pub fn partial_encode(
        &self, 
        context: &mut E, 
        data: &mut dyn Iterator<Item = Bit>
    ) -> Result<EncoderResult, Box<dyn Error>>;

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

Base trait for all data encoders. The generic type should contain data need by the encoder implementation.

Required methods

pub fn partial_encode(
    &self,
    context: &mut E,
    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.

Arguments

• context - context of the steganography method, can contain various needed info like pivot etc.
• data - data iterator which return Bit with each iteration

Returns

It returns whether the encoding was successful. See EncoderResult and EncodingError.
