Crate deps_core 

Core abstractions for deps-lsp.

This crate provides the foundational traits and utilities used across all ecosystem-specific implementations (Cargo, npm, PyPI, etc.).

Architecture

deps-core defines:

• Traits: Registry, Version, Metadata, Ecosystem, ParseResult
• HTTP Cache: Shared caching layer with ETag/Last-Modified validation
• Error Types: Unified error handling across all ecosystems

Modules

cache

completion

Core completion infrastructure for deps-lsp.

deps_dev

Supply-chain trust signal via deps.dev API v3.

ecosystem

ecosystem_registry

error

freshness

Release-freshness signal: publish-time tracking and cooldown-window checks.

fs_probe

Counted filesystem probe funnel, shared by every ecosystem crate’s config-file cache.

github

Shared GitHub tags-API client, used by every ecosystem that resolves package versions from GitHub repository tags rather than a dedicated package registry (deps-swift, deps-github-actions).

json_ast

Shared JSONC-AST helpers for recovering exact dependency source positions (#613).

lockfile

Lock file parsing abstractions.

lsp_helpers

Shared LSP response builders.

macros

Macro utilities for reducing boilerplate in ecosystem implementations.

mtime_cache

Generic per-path, mtime-gated file cache shared by every ecosystem config-file cache (deps-cargo’s .cargo/config.toml/$CARGO_HOME/config.toml, deps-npm’s .npmrc).

net_policy

Reachability policy for registry index URLs declared by a workspace file.

osv

OSV.dev vulnerability scanning.

package

Newtypes distinguishing package names, version requirement strings, and concrete resolved versions.

pagination

Generic paginated-fetch loop for a git-tags-shaped REST API returning per_page=100 pages.

parser

registry

secret

Generic “never surfaced via Debug/Display” wrapper for in-memory secrets.

test_util

Test fixtures and helpers shared across ecosystem crates.

version_matcher

Version requirement matching abstractions.

Macros

impl_dependency

Implement the Dependency trait for a struct.

impl_metadata

Implement Metadata trait for a struct.

impl_parse_result

Implement ParseResult trait for a struct.

impl_version
