Struct zip::read::ZipArchive

pub struct ZipArchive<R: Read + Seek> { /* fields omitted */ }

Wrapper for reading the contents of a ZIP file.

fn doit() -> zip::result::ZipResult<()>
{
    use std::io::prelude::*;

    // For demonstration purposes we read from an empty buffer.
    // Normally a File object would be used.
    let buf: &[u8] = &[0u8; 128];
    let mut reader = std::io::Cursor::new(buf);

    let mut zip = zip::ZipArchive::new(reader)?;

    for i in 0..zip.len()
    {
        let mut file = zip.by_index(i).unwrap();
        println!("Filename: {}", file.name());
        let first_byte = file.bytes().next().unwrap()?;
        println!("{}", first_byte);
    }
    Ok(())
}

println!("Result: {:?}", doit());

Methods

impl<R: Read + Seek> ZipArchive<R>

pub fn new(reader: R) -> ZipResult<ZipArchive<R>>

Opens a Zip archive and parses the central directory

pub fn len(&self) -> usize

Number of files contained in this zip.

fn iter() {
    let mut zip = zip::ZipArchive::new(std::io::Cursor::new(vec![])).unwrap();

    for i in 0..zip.len() {
        let mut file = zip.by_index(i).unwrap();
        // Do something with file i
    }
}

pub fn is_empty(&self) -> bool

Whether this zip archive contains no files

pub fn offset(&self) -> u64

Get the offset from the beginning of the underlying reader that this zip begins at, in bytes.

Normally this value is zero, but if the zip has arbitrary data prepended to it, then this value will be the size of that prepended data.

pub fn comment(&self) -> &[u8]

Get the comment of the zip archive.

pub fn file_names(&self) -> impl Iterator<Item = &str>

Returns an iterator over all the file and directory names in this archive.

pub fn by_name<'a>(&'a mut self, name: &str) -> ZipResult<ZipFile<'a>>

Search for a file entry by name

pub fn by_index<'a>(&'a mut self, file_number: usize) -> ZipResult<ZipFile<'a>>

Get a contained file by index

pub fn into_inner(self) -> R

Unwrap and return the inner reader object

The position of the reader is undefined.

Trait Implementations

fn clone(&self) -> ZipArchive<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Debug + Read + Seek> Debug for ZipArchive<R>

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

Formats the value using the given formatter.
