Struct App 

pub struct App { /* private fields */ }

Client for the gestalt.provider.v1.App service.

Implementations

impl App

pub fn new(channel: Channel) -> Self

Creates a client over an established channel.

pub fn with_timeout(self, timeout: Duration) -> Self

Sets a deadline applied to every unary call; calls that run past it fail with DEADLINE_EXCEEDED. Streaming calls are unaffected.

pub fn with_context(self, context: RequestContext) -> Self

Sets the default request context, injected into outgoing requests that do not carry one.

pub async fn connect() -> Result<Self, GestaltError>

Connects to the app host service described by the environment.

pub async fn connect_named(name: &str) -> Result<Self, GestaltError>

Connects to the named app host-service binding.

pub async fn invoke( &mut self, app: String, operation: String, params: Option<Map<String, Value>>, options: AppInvokeOptions, ) -> Result<Value, InvokeError>

Calls gestalt.provider.v1.App.Invoke. The result decodes with the standard JSON operation envelope semantics; payload failures surface as InvokeError.

pub async fn invoke_raw( &mut self, request: AppInvokeRequest, ) -> Result<OperationResult, GestaltError>

Calls gestalt.provider.v1.App.Invoke with the full request and response messages.

pub async fn invoke_stream( &mut self, request: AppInvokeRequest, ) -> Result<AppInvokeStreamStream, GestaltError>

InvokeStream is the streaming counterpart of Invoke. It is gRPC-only (no REST binding) and shares Invoke’s request shape, authorization, and signature policy. The first response frame is always InvokeMetadata; subsequent frames carry data bytes from the operation’s stream response. A mid-stream error may emit a trailing metadata frame with an error status followed by a JSON error body, after which the stream ends.

Calls gestalt.provider.v1.App.InvokeStream, returning a stream of converted frames.

pub async fn invoke_graphql( &mut self, app: String, document: String, options: AppInvokeGraphQLOptions, ) -> Result<OperationResult, GestaltError>

Calls gestalt.provider.v1.App.InvokeGraphQL.

pub async fn invoke_graphql_raw( &mut self, request: AppInvokeGraphQLRequest, ) -> Result<OperationResult, GestaltError>

Calls gestalt.provider.v1.App.InvokeGraphQL with the full request and response messages.
