Crate rlvgl_playit 

Mini-playwright test driver for rlvgl.

rlvgl-playit provides input injection, widget queries by tag, and framebuffer pixel inspection over a pluggable transport (serial, in-process, etc.).

Architecture

test host                       target / simulator
──────────                      ──────────────────
"T100,200\n"  ──► transport ──► PlayitExecutor::poll()

                                  ├─ EventSpec → Event
                                  ├─ WidgetNode::dispatch_event()

Modules

Module	Purpose
command	Command, EventSpec, KeySpec, QuerySpec, DumpSpec, TouchPointSpec
response	Response, StatusData
protocol	Text wire codec (parse / format)
transport	PlayitTransport byte-level I/O trait
executor	PlayitExecutor, EventPipeline — main poll loop + gesture routing
recorder	EventRecorder — timed input capture for replay
tag	find_by_tag / find_by_tag_mut tree walkers
framebuffer	FramebufferReader pixel inspection trait
[tcp]	Loopback TCP transport for simulator / host automation (std)

no_std support

The crate is no_std-compatible by default with no allocator required. Enable alloc for heap-backed helpers or std for standard-library integrations.

Modules

command

Command types for the playit test driver.

executor

The playit executor: polls a transport, parses commands, and dispatches them against the widget tree.

framebuffer

Framebuffer pixel inspection trait.

protocol

Text wire protocol codec.

recorder

Timed event recorder.

response

Response types returned by the playit executor.

tag

Depth-first tag lookup in a WidgetNode tree.

transport

Transport abstraction for the playit driver.
