Crate gpui_tea 

Build Elm-style GPUI programs with composable models, commands, and subscriptions.

gpui_tea packages the runtime primitives needed to drive a The Elm Architecture style application on top of gpui. The crate exposes:

• Model for state transitions and rendering
• Program for mounting and running a model inside GPUI
• Command for immediate, foreground, and background effects
• Subscription and Subscriptions for long-lived external event sources
• ModelContext and ChildScope for nesting child models under explicit paths

Most applications implement Model and mount it with Program::mount() or ModelExt::into_program().

Structs

ChildPath

Identify a model’s position inside a nested program tree.

ChildScope

Bridge a child Model into a parent model’s message space.

Command

Describe work the runtime should perform after a model transition.

Dispatcher

Send messages back into a mounted crate::Program.

Key

Identify a keyed effect or subscription across reconciliations.

ModelContext

Carry structural context for a Model invocation.

Program

Host a mounted Model inside the GPUI runtime.

ProgramConfig

Configure runtime observability hooks and queue behavior.

ProgramId

Identify a mounted program instance in observability output.

RuntimeSnapshot

Snapshot runtime bookkeeping for a mounted Program.

Subscription

Declare a long-lived external event source for a program.

SubscriptionContext

Expose runtime services while constructing a Subscription.

Subscriptions

Collect a set of unique Subscription values.

TelemetryEnvelope

Wrap a telemetry event together with its metadata.

TelemetryMetadata

Carry metadata emitted with each TelemetryEvent.

View

Wrap a GPUI element returned from crate::Model::view().

Enums

CommandKind

Classify how a Command interacts with the runtime.

Error

Report runtime and subscription construction failures.

QueueOverflowAction

Describe the action taken when a queue reaches capacity.

QueuePolicy

Define how the runtime handles queue backpressure.

RuntimeEvent

Describe high-level runtime events intended for application observers.

SubHandle

Hold the runtime resource that keeps a subscription alive.

TelemetryEvent

Describe detailed runtime telemetry intended for machine consumption.

Traits

IntoView

Convert a GPUI element into a View.

Model

Define state, message handling, and rendering for a TEA program.

ModelExt

Mount a Model as a fully initialized Program.

Functions

observe_metrics_telemetry

Record a TelemetryEnvelope as metrics counters and gauges.

observe_tracing_telemetry

Record a TelemetryEnvelope as tracing events.

Type Aliases

Result

Alias the crate-wide result type.

Derive Macros

Composite

Derive child-model forwarding helpers for a composite model struct.
