Struct EncoderConfig

pub struct EncoderConfig {
    pub match_src: Option<SrcMatcherConfig>,
    pub match_trgt: Option<TrgtMatcherConfig>,
    pub sec_comp: Option<SecondaryCompression>,
    pub format: Format,
    pub output_segment_size: usize,
    pub naive_tests: Option<LargerTrgtNaiveTests>,
    pub lazy_escape_len: Option<usize>,
}

Configuration for the encoder.

Default values are:

• match_src: Some(SrcMatcherConfig::new_from_compression_level(3))
• match_target: None
• sec_comp: None
• format: Interleaved
• output_segment_size: MAX_WIN_SIZE
• naive_tests: None
• lazy_escape_len: Some(45)

Fields

match_src: Option<SrcMatcherConfig>

Do we consider the src file as a dictionary to find matches? If so (Some(_)), any preferences set in the MatcherConfig will be used. Default Value: Some(SrcMatcherConfig::new_from_compression_level(3))

match_trgt: Option<TrgtMatcherConfig>

Whether to use the output file in an attempt to compress itself. If so (Some(_)), any preferences set in the MatcherConfig will be used. Default Value: None

sec_comp: Option<SecondaryCompression>

None for no secondary compression. Default Value: None

format: Format

Whether to interleave or segregate the Add bytes. Default Value: Interleaved

output_segment_size: usize

The size of the output window. Default Value: MAX_WIN_SIZE The minimum value is MAX_INST_SIZE.

naive_tests: Option<LargerTrgtNaiveTests>

The types of naive tests to run. Default Value: None

lazy_escape_len: Option<usize>

The length of a match that will end the lazy matching sequence. Default Value: Some(45)

pub fn set_lazy_escape_len(self, len: usize) -> Self

pub fn comp_level( level: usize, match_trgt: bool, sec_comp: Option<SecondaryCompression>, ) -> Self

Use the short hand compression level. If match_trgt is true, the same compression level will be used to set the TrgtMatcherConfig. If secondary compression is Some(_), the format will be Segregated, else Interleaved.
