Struct flate2::GzHeader

source ·
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 Header

source

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

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

source

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

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

source

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

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

source

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.

source

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.

Trait Implementations§

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

Formats the value using the given formatter. Read more

impl PartialEq<Header> for Header

source§

fn eq(&self, other: &Header) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
