everruns-provider

Lean provider and LLM abstractions shared by the Everruns Framework and provider crates.

everruns-provider owns credential-free model identity, the ChatDriver boundary, provider assembly, protocol drivers, stream/retry helpers, model profiles, typed IDs, credential schemas, and the LLM error taxonomy.

It is a focused implementation crate in the Everruns ecosystem. Framework application authors normally use the curated surface through everruns; provider implementers and low-level hosts depend here directly to avoid pulling in the agent-loop kernel.

The default http feature provides the shared protocol implementations and selects the ring Rustls provider before constructing their clients. Contract- only consumers can use default-features = false to avoid HTTP and TLS dependencies entirely. The tls-ring feature exposes the idempotent startup initializer independently for binaries that assemble multiple TLS stacks.

Quick Example

use everruns_provider::ModelSpec;

let model = ModelSpec::on("company-gateway", "assistant-v2");
assert_eq!(model.provider.as_str(), "company-gateway");
assert_eq!(model.model, "assistant-v2");
