Struct gio::ZlibCompressor

#[repr(transparent)]
pub struct ZlibCompressor { /* private fields */ }

ZlibCompressor is an implementation of Converter that compresses data using zlib.

Implements

glib::ObjectExt, ConverterExt, ConverterExtManual

Implementations

impl ZlibCompressor

pub fn new(format: ZlibCompressorFormat, level: i32) -> ZlibCompressor

Creates a new ZlibCompressor.

format

The format to use for the compressed data

level

compression level (0-9), -1 for default

Returns

a new ZlibCompressor

pub fn file_info(&self) -> Option<FileInfo>

Returns the property::ZlibCompressor::file-info property.

Returns

a FileInfo, or None

pub fn set_file_info(&self, file_info: Option<&FileInfo>)

Sets file_info in self. If non-None, and self’s property::ZlibCompressor::format property is ZlibCompressorFormat::Gzip, it will be used to set the file name and modification time in the GZIP header of the compressed data.

Note: it is an error to call this function while a compression is in progress; it may only be called immediately after creation of self, or after resetting it with ConverterExt::reset().

file_info

a FileInfo

pub fn format(&self) -> ZlibCompressorFormat

pub fn level(&self) -> i32

pub fn connect_file_info_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId

Trait Implementations

impl Clone for ZlibCompressor

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ZlibCompressor

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

Formats the value using the given formatter.

impl Display for ZlibCompressor

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

Formats the value using the given formatter.

impl Hash for ZlibCompressor

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ZlibCompressor

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for ZlibCompressor

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for ZlibCompressor

fn eq(&self, other: &OT) -> 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.

impl<OT: ObjectType> PartialOrd<OT> for ZlibCompressor

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for ZlibCompressor

fn static_type() -> Type

Returns the type identifier of Self.
