pub struct GzHeader { /* private fields */ }
Expand description
A structure representing the header of a gzip stream.
The header can contain metadata about the file that was compressed, if present.
Implementations§
source§impl GzHeader
impl GzHeader
sourcepub fn filename(&self) -> Option<&[u8]>
pub fn filename(&self) -> Option<&[u8]>
Returns the filename
field of this gzip stream’s header, if present.
sourcepub fn extra(&self) -> Option<&[u8]>
pub fn extra(&self) -> Option<&[u8]>
Returns the extra
field of this gzip stream’s header, if present.
sourcepub fn comment(&self) -> Option<&[u8]>
pub fn comment(&self) -> Option<&[u8]>
Returns the comment
field of this gzip stream’s header, if present.
sourcepub fn operating_system(&self) -> u8
pub fn operating_system(&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.
sourcepub fn mtime(&self) -> u32
pub fn mtime(&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.
sourcepub fn mtime_as_datetime(&self) -> Option<SystemTime>
pub fn mtime_as_datetime(&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.
