Module uv_iotask

The I/O task runs in its own single-threaded scheduler. By using the interact function you can execute code in a uv callback.

Enum `iotask`

Used to abstract-away direct interaction with a libuv loop.

Variants

iotask_({async_handle: *ll::uv_async_t, op_chan: chan<iotask_msg>,})

Function `exit`

fn exit(iotask: iotask)

Shut down the I/O task

Is used to signal to the loop that it should close the internally-held async handle and do a sanity check to make sure that all other handles are closed, causing a failure otherwise.

Function `interact`

unsafe fn interact(iotask: iotask, -cb: fn~(*c_void))

Provide a callback to be processed by iotask

The primary way to do operations again a running iotask that doesn't involve creating a uv handle via safe_handle

Warning

This function is the only safe way to interact with any iotask. Using functions in the uv::ll module outside of the cb passed into this function is very dangerous.

Arguments

iotask - a uv I/O task that you want to do operations against
cb - a function callback to be processed on the running loop's thread. The only parameter passed in is an opaque pointer representing the running uv_loop_t*. In the context of this callback, it is safe to use this pointer to do various uv_* API calls contained within the uv::ll module. It is not safe to send the loop_ptr param to this callback out via ports/chans.
