Implementations

impl Metadata

pub fn is_encrypted(&self) -> bool

Returns true if this file is encrypted.

pub fn name(&self) -> &str

Gets the name of this entry.

pub fn comment(&self) -> &str

Gets the comment of this entry.

pub fn read<R: BufRead + Seek>(&self, reader: R) -> Result<impl Read + use<R>>

Returns a reader with the content of the file.

Unsupported compression methods and encrypted files will return an error.

pub fn read_stored<R: Read + Seek>(&self, reader: R) -> Result<Take<R>>

Returns a reader with the content of the file.

Errors if the file is compressed, encrypted or corrupted. Is is not necessary to use Metadata::content_checker on the result.

It is useful if you know that the file is stored as-is and you want to take advantage of the BufReader or the Seek implementation.

pub fn read_raw<R: Read + Seek>(&self, reader: R) -> Result<Take<R>>

Returns a reader with the raw, uncompressed, content of the file.

The uncompressed content should be checked with content_checker.

pub fn content_checker<R: Read>(&self, reader: R) -> impl Read + use<R>

Wraps a reader to check that its content matches this metadata.

It is particularly useful in combinaison of read_raw.

pub fn extract<R: BufRead + Seek>( &self, reader: &mut R, root: impl AsRef<Path>, ) -> Result<()>

Extracts this entry as if the root of the archive was at root.

Trait Implementations

impl Debug for Metadata

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

Formats the value using the given formatter.
