DataInputStream

Provided Methods

fn byte_order(&self) -> DataStreamByteOrder

Gets the byte order for the data input stream.

Returns

the @self’s current #GDataStreamByteOrder.

fn newline_type(&self) -> DataStreamNewlineType

Gets the current newline type for the @self.

Returns

#GDataStreamNewlineType for the given @self.

fn read_byte( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<u8, Error>

Reads an unsigned 8-bit/1-byte value from @self.

cancellable

optional #GCancellable object, None to ignore.

Returns

an unsigned 8-bit/1-byte value read from the @self or 0 if an error occurred.

fn read_int16( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<i16, Error>

Reads a 16-bit/2-byte value from @self.

In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order() and g_data_input_stream_set_byte_order().

cancellable

optional #GCancellable object, None to ignore.

Returns

a signed 16-bit/2-byte value read from @self or 0 if an error occurred.

fn read_int32( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<i32, Error>

Reads a signed 32-bit/4-byte value from @self.

In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order() and g_data_input_stream_set_byte_order().

If @cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional #GCancellable object, None to ignore.

Returns

a signed 32-bit/4-byte value read from the @self or 0 if an error occurred.

fn read_int64( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<i64, Error>

Reads a 64-bit/8-byte value from @self.

In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order() and g_data_input_stream_set_byte_order().

If @cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional #GCancellable object, None to ignore.

Returns

a signed 64-bit/8-byte value read from @self or 0 if an error occurred.

fn read_uint16( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<u16, Error>

Reads an unsigned 16-bit/2-byte value from @self.

In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order() and g_data_input_stream_set_byte_order().

cancellable

optional #GCancellable object, None to ignore.

Returns

an unsigned 16-bit/2-byte value read from the @self or 0 if an error occurred.

fn read_uint32( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<u32, Error>

Reads an unsigned 32-bit/4-byte value from @self.

In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order() and g_data_input_stream_set_byte_order().

If @cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional #GCancellable object, None to ignore.

Returns

an unsigned 32-bit/4-byte value read from the @self or 0 if an error occurred.

fn read_uint64( &self, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<u64, Error>

Reads an unsigned 64-bit/8-byte value from @self.

In order to get the correct byte order for this read operation, see g_data_input_stream_get_byte_order().

If @cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error IOErrorEnum::Cancelled will be returned.

cancellable

optional #GCancellable object, None to ignore.

Returns

an unsigned 64-bit/8-byte read from @self or 0 if an error occurred.

fn set_byte_order(&self, order: DataStreamByteOrder)

This function sets the byte order for the given @self. All subsequent reads from the @self will be read in the given @order.

order

a #GDataStreamByteOrder to set.

fn set_newline_type(&self, type_: DataStreamNewlineType)

Sets the newline type for the @self.

Note that using G_DATA_STREAM_NEWLINE_TYPE_ANY is slightly unsafe. If a read chunk ends in “CR” we must read an additional byte to know if this is “CR” or “CR LF”, and this might block if there is no more data available.

type_

the type of new line return as #GDataStreamNewlineType.

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

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
