Struct gio::MemoryOutputStream

source ·
#[repr(transparent)]
pub struct MemoryOutputStream { /* private fields */ }
Expand description

MemoryOutputStream is a class for using arbitrary memory chunks as output for GIO streaming output operations.

As of GLib 2.34, MemoryOutputStream trivially implements PollableOutputStream: it always polls as ready.

Properties

data

Pointer to buffer where data will be written.

Readable | Writeable | Construct Only

data-size

Size of data written to the buffer.

Readable

destroy-function

Function called with the buffer as argument when the stream is destroyed.

Readable | Writeable | Construct Only

realloc-function

Function with realloc semantics called to enlarge the buffer.

Readable | Writeable | Construct Only

size

Current size of the data buffer.

impl<O> PollableOutputStreamExt for Owhere O: IsA<PollableOutputStream>,

source§

fn can_poll(&self) -> bool

Checks if self is actually pollable. Some classes may implement PollableOutputStream but have only certain instances of that class be pollable. If this method returns false, then the behavior of other PollableOutputStream methods is undefined. Read more
source§

fn is_writable(&self) -> bool

Checks if self can be written. Read more
source§

fn write_nonblocking( &self, buffer: &[u8], cancellable: Option<&impl IsA<Cancellable>> ) -> Result<isize, Error>

Attempts to write up to count bytes from buffer to self, as with OutputStreamExt::write(). If self is not currently writable, this will immediately return IOErrorEnum::WouldBlock, and you can use PollableOutputStreamExtManual::create_source() to create a glib::Source that will be triggered when self is writable.

fn create_source<F, C>( &self, cancellable: Option<&C>, name: Option<&str>, priority: Priority, func: F ) -> Sourcewhere F: FnMut(&O) -> Continue + 'static, C: IsA<Cancellable>,

Creates a glib::Source that triggers when self can be written, or cancellable is triggered or an error occurs. The callback on the source is of the GPollableSourceFunc type. Read more
