Struct ZlibCompressor

pub struct ZlibCompressor { /* private fields */ }

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

Properties

file-info

If set to a non-None #GFileInfo object, and #GZlibCompressor:format is ZlibCompressorFormat::Gzip, the compressor will write the file name and modification time from the file info to the GZIP header.

Readable | Writeable

format

The format of the compressed data.

Readable | Writeable | Construct Only

level

The level of compression from 0 (no compression) to 9 (most compression). -1 for the default level.

GLib type: GObject with reference counted clone semantics.

Implementations

impl ZlibCompressor

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

Creates a new #GZlibCompressor.

format

The format to use for the compressed data

level

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

Returns

a new #GZlibCompressor

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

Returns the #GZlibCompressor:file-info property.

Returns

a #GFileInfo, or None

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

Sets @file_info in @self. If non-None, and @self’s #GZlibCompressor: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 g_converter_reset().

file_info

a #GFileInfo

pub fn format(&self) -> ZlibCompressorFormat

The format of the compressed data.

pub fn level(&self) -> i32

The level of compression from 0 (no compression) to 9 (most compression). -1 for the default level.

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

Trait Implementations

impl Clone for ZlibCompressor

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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 HasParamSpec for ZlibCompressor

type ParamSpec = ParamSpecObject

type SetValue = ZlibCompressor

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, ZlibCompressor>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ZlibCompressor

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

where H: Hasher,

Hashes the memory address of this object.

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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.
