Struct zip::read::ZipFile [−][src]
pub struct ZipFile<'a> { /* fields omitted */ }
Expand description
A struct for reading a zip file
Implementations
Methods for retrieving information on zip files
Get the name of the file
Warnings
It is dangerous to use this name directly when extracting an archive.
It may contain an absolute path (/etc/shadow
), or break out of the
current directory (../runtime
). Carelessly writing to these paths
allows an attacker to craft a ZIP archive that will overwrite critical
files.
You can use the ZipFile::enclosed_name
method to validate the name
as a safe path.
Get the name of the file, in the raw (internal) byte representation.
The encoding of this data is currently undefined.
👎 Deprecated since 0.5.7: by stripping ..
s from the path, the meaning of paths can change.
mangled_name
can be used if this behaviour is desirable

s from the path, the meaning of paths can change.
mangled_name

Get the name of the file in a sanitized form. It truncates the name to the first NULL byte, removes a leading ‘/’ and removes ‘..’ parts.
Rewrite the path, ignoring any path components with special meaning.
- Absolute paths are made relative
ParentDir
s are ignored- Truncates the filename at a NULL byte
This is appropriate if you need to be able to extract something from
any archive, but will easily misrepresent trivial paths like
foo/../bar
as foo/bar
(instead of bar
). Because of this,
ZipFile::enclosed_name
is the better option in most scenarios.
Ensure the file path is safe to use as a Path
.
- It can’t contain NULL bytes
- It can’t resolve to a path outside the current directory
foo/../bar
is fine,foo/../../bar
is not. - It can’t be an absolute path
This will read well-formed ZIP files correctly, and is resistant
to path-based exploits. It is recommended over
ZipFile::mangled_name
.
Get the compression method used to store the file
Get the size of the file in the archive
Get the time the file was last modified
Get the extra data of the zip header for this file
Get the starting offset of the data of the compressed file
Get the starting offset of the zip header for this file
Get the starting offset of the zip header in the central directory for this file
