Struct GzHeader 

pub struct GzHeader { /* private fields */ }

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

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

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

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

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

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

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

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.

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.

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

impl Clone for GzHeader

fn clone(&self) -> GzHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GzHeader

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

Formats the value using the given formatter.

impl Default for GzHeader

fn default() -> GzHeader

Returns the “default value” for a type.

impl PartialEq for GzHeader

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

Tests for self and other values to be equal, and is used by ==.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
