Crate daml_grpc 

Daml ledger GRPC API.

This library provides a client for the Daml ledger GRPC API.

Example

The following example demonstrates creating a DamlGrpcClient using the DamlGrpcClientBuilder, then creating a DamlSimpleExecutor using the DamlSimpleExecutorBuilder and finally creating and submitting a DamlCreateCommand to the ledger:

let client = DamlGrpcClientBuilder::uri("http://localhost:8082").connect().await?;
let executor = DamlSimpleExecutorBuilder::new(&client).act_as("Alice").build()?;
let template_id = DamlIdentifier::new("...", "Fuji.PingPong", "Ping");
let record = DamlRecord::new(vec![], None::<DamlIdentifier>);
let command = DamlCreateCommand::new(template_id, record);
let create_event = executor.execute_create(command).await?;

Note that Daml commands such as DamlCreateCommand can be automatically generated for existing Daml templates using the various functions and macros provided in the daml-codegen crate.

Note also that the daml_value macro is provided to simplify the construction of DamlRecord and DamlValue types.
