    extra: Option<Vec<u8>>,

Expand description

A structure representing the header of a gzip stream.

The header can contain metadata about the file that was compressed, if present.

Fields

extra: Option<Vec<u8>>filename: Option<Vec<u8>>comment: Option<Vec<u8>>operating_system: u8mtime: u32

Implementations

Returns the filename field of this gzip stream’s header, if present.

Returns the extra field of this gzip stream’s header, if present.

Returns the comment field of this gzip stream’s header, if present.

Returns the operating_system field of this gzip stream’s header.

There are predefined values for various operating systems. 255 means that the value is unknown.

This gives the most recent modification time of the original file being compressed.

The time is in Unix format, i.e., seconds since 00:00:00 GMT, Jan. 1, 1970. (Note that this may cause problems for MS-DOS and other systems that use local rather than Universal time.) If the compressed data did not come from a file, mtime is set to the time at which compression started. mtime = 0 means no time stamp is available.

The usage of mtime is discouraged because of Year 2038 problem.

Returns the most recent modification time represented by a date-time type. Returns None if the value of the underlying counter is 0, indicating no time stamp is available.

The time is measured as seconds since 00:00:00 GMT, Jan. 1 1970. See mtime for more detail.
