Struct zifu::InputZIPArchive

pub struct InputZIPArchive<F: ReadBytesExt + Seek> { /* fields omitted */ }

This struct is for providing the internal processing API used in the zifu CLI.

This helps you to create e.g. GUI version

This is initialized by ::new() method.

Implementations

impl<F> InputZIPArchive<F> where
    F: ReadBytesExt + Seek, 

pub fn new(handler: F) -> Result<Self>

Returns an initialized instance.

Arguments

• handler - File handler representing the input ZIP file (Bufreader<File> recommended)

pub fn diagnose_file_name_encoding(&self) -> FileNamesDiagnosis

Returns the file name encoding diagnossis.

For details, see the description for FileNamesDiagnosis.

pub fn get_filename_decoder_index(
    &self,
    decoders_list: &[&dyn IDecoder]
) -> Option<usize>

Test applying given decoders to the file names and returns the index of the first successful one.

If nothing is successful for all names, returns None.

Arguments

• decoders_list - list of decoders; the former the higher priority.

pub fn get_file_names_list(
    &self,
    legacy_decoder: &dyn IDecoder
) -> Vec<FileNameEntry>

Returns a list of file names (including whether they are explicitly encoded in UTF-8).

Arguments

• legacy_decoder - used for implicitly-encoded file names.

pub fn convert_central_directory_file_names(
    &mut self,
    legacy_decoder: &dyn IDecoder
)

Changes encoding of file names in central directories in ZIP archive

This affects only on .cd_entries; The contents of the original ZIP file will not be overwritten.

Arguments

• legacy_decoder: decoder for file names with implicit encoding

pub fn output_archive_with_central_directory_file_names<G: WriteBytesExt>(
    &mut self,
    dest_handler: &mut G
) -> Result<()>

Outputs the ZIP archive to the given handler.

File names in local file headers will be ignored. That in central directories are used instead.

Arguments

• dest_handler - The file handler representing for the output file.

pub fn check_unsupported_zip_type(&self) -> Result<(), ZipReadError>

Returns Err(ZipReadError) if the archive has unsupported features (e.g. central directory encryption)
