orpc-procedure

Type-erased execution engine for oRPC procedures.

Overview

This is the lowest-level crate in the orpc-rs stack. It defines the core abstractions that all other crates build upon:

• ErasedProcedure<TCtx> — A type-erased procedure that accepts dynamic input and produces a ProcedureStream
• ProcedureStream — Unified output type supporting both single-value (from_future) and streaming (from_stream) results
• DynInput / DynOutput — Type-erased wrappers for serde-compatible values
• ErasedSchema — Trait for type-erased input/output schemas (extended by orpc-specta)

Usage

Most users should use the higher-level orpc crate instead. This crate is useful for:

• Building custom integrations (server adapters, client code generators)
• Working with procedures after type erasure
• Implementing custom schema adapters

use orpc_procedure::*;

let proc = ErasedProcedure::new(
    |ctx: MyCtx, input: DynInput| {
        ProcedureStream::from_future(async move {
            let name: String = input.deserialize()?;
            Ok(DynOutput::new(format!("Hello, {name}!")))
        })
    },
    Route::default(),
    Meta::default(),
);
