deps-core

Core abstractions for deps-lsp: traits, caching, and generic LSP handlers.

This crate provides the shared infrastructure used by ecosystem-specific crates (deps-cargo, deps-npm, deps-pypi, deps-go).

Features

• EcosystemHandler Trait — Unified interface for all package ecosystems
• LockFileProvider Trait — Abstract lock file parsing for resolved versions
• Generic LSP Handlers — generate_inlay_hints, generate_hover, generate_code_actions, generate_diagnostics
• HTTP Cache — ETag/Last-Modified caching for registry requests
• Version Matchers — Semver and PEP 440 version matching
• Error Types — Unified error handling with thiserror

Usage

[dependencies]
deps-core = "0.5"

use deps_core::{EcosystemHandler, HttpCache, PackageRegistry};

Architecture

// Implement EcosystemHandler for your ecosystem
#[async_trait]
impl EcosystemHandler for MyHandler {
    type Registry = MyRegistry;
    type Dependency = MyDependency;
    // ...
}

// Use generic handlers
let hints = generate_inlay_hints::<MyHandler>(&handler, &deps).await;
let hover = generate_hover_info::<MyHandler>(&handler, &dep, &versions);
