Struct `GzHeader`

struct GzHeader { ... }

A structure representing the header of a gzip stream.

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

Implementations

`impl GzHeader`

fn filename(self: &Self) -> Option<&[u8]>

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

fn extra(self: &Self) -> Option<&[u8]>

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

fn comment(self: &Self) -> Option<&[u8]>

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

fn operating_system(self: &Self) -> u8

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.

fn mtime(self: &Self) -> u32

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.

fn mtime_as_datetime(self: &Self) -> Option<SystemTime>

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.
