Struct ZipStreamFileMetadata

Expand description

Additional metadata for the file.

Implementations§

Source§

impl ZipStreamFileMetadata

Source

pub fn name(&self) -> &str

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.

Source

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

Get the name of the file, in the raw (internal) byte representation.

The encoding of this data is currently undefined.

Source

pub fn mangled_name(&self) -> PathBuf

Rewrite the path, ignoring any path components with special meaning.

  • Absolute paths are made relative
  • ParentDirs 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.

Source

pub fn enclosed_name(&self) -> Option<&Path>

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.

Source

pub fn is_dir(&self) -> bool

Returns whether the file is actually a directory

Source

pub fn is_file(&self) -> bool

Returns whether the file is a regular file

Source

pub fn comment(&self) -> &str

Get the comment of the file

Source

pub fn data_start(&self) -> u64

Get the starting offset of the data of the compressed file

Source

pub fn unix_mode(&self) -> Option<u32>

Get unix mode for the file

where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Use this to cast from one trait object type to another. This method is more customizable than the dyn_cast method. Here you can also specify the “source” trait from which the cast is defined. This can for example allow using casts from a supertrait of the current trait object. Read more
