Crate incular_devtools_protocol 

Typed, versioned wire protocol between a running Incular application (the target) and Incular DevTools.

This crate intentionally depends only on serde: it must stay usable by the standalone DevTools UI, the in-target agent, and offline tooling without pulling in the framework runtime or renderer.

Structs

CacheReport

DebugProperty

DeepFrameTrace

Bounded trace batch for one target/window frame. truncated and dropped_events make partial data impossible to mistake for a full trace.

DevLayerId

DevRenderId

DevSemanticsId

DevSignalId

DevWidgetId

DevWindowId

DiscoveryRecord

Per-user discovery record written by devtools-enabled targets so the DevTools launcher can list running applications without port scanning.

ElementState

FlexChildInspection

FrameRecordEvent

FrameTimingsWire

Hello

First message sent by either side after the WebSocket opens. The target validates auth_token against its random session token before accepting any further frame.

LayoutHistoryEntry

LayoutInspection

Read-only geometry captured from the retained layout result. This is a snapshot, never a handle to a mutable render object; DevTools must not run layout again merely to answer an inspection request.

TargetInfo

One real, hierarchical per-node timing recorded only in Deep mode.

ErrorCode

InvalidationReason

LayoutDetails

Layout-strategy-specific, compact inspection data. Every coordinate and allocation comes from the completed retained layout pass; the DevTools UI only visualizes this data.

Message

One wire frame after the handshake.

PeerKind

RequestMethod

DevTools → target. Every request produces exactly one ResponsePayload correlated by request_id.

ResponsePayload

TargetEvent

Target → DevTools unsolicited events (bounded queues apply upstream).

TracePhase

TreeDelta

Constants

DEVTOOLS_VERSION

DevTools implementation version carried in the handshake for diagnostics.

MIN_SUPPORTED_PROTOCOL_VERSION

Oldest wire protocol that remains compatible with this implementation. Protocol 2 only adds typed property-edit requests, so protocol 1 clients can continue to inspect a protocol 2 target.

PROTOCOL_VERSION

Current wire protocol version.

Functions

check_hello

Validates a handshake from the other side. Targets call this with the client hello (expecting PeerKind::Devtools) and vice versa.
