Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.10.0] - 2024-12-09

Added

  • Catalog::scope and Catalog::current allow setting and accessing a "current" catalog in a task-local context
    • Requires new tokio crate feature
  • Lazy<T> injection spec that delays the creation of a value until it's requested
    • Can be used to delay initialization of expensive values that are rarely used
    • Can be used in combination with Catalog::scope to inject values registered dynamically

[0.9.3] - 2024-12-06

Changed

  • Upgraded to thiserror v2 dependency

[0.9.2] - 2024-10-02

Added

  • Catalog::builder() and catalog.builder_chained() shortcuts
  • New examples directory to showcase DI patterns and integrations

[0.9.1] - 2024-08-15

Fixed

  • Catalog::builders_for_with_meta() works corectly for chained catalogs

[0.9.0] - 2024-07-29

Added

  • It's now possible to associate custom static metadata with builders: 
    #[component]
#[interface(dyn EventHandler)]
#[meta(EventHandlerDesc { event_type: "A"})]
#[meta(EventHandlerDesc { event_type: "B"})]
struct EventHandlerAB;
  • New BuilderExt trait was added to provide convenient access to metadata and interfaces
  • New Catalog::builders_for_with_meta() allows to filter builders by metadata with a custom predicate

Changed

  • Builder::interfaces method was changed to iteration via callback to avoid allocating a Vec

[0.8.1] - 2024-05-27

Fixed

  • Fixed pedantic linter warnings

[0.8.0] - 2023-11-27

Added

  • Added interface(T) macro attribute to provide default interface bindings for the component builders, allowing to cut down verboseness of catalog configuration. Example: 
    trait Iface {}

#[dill::component]
#[dill::interface(dyn Iface)]
struct Impl;

// Automatically does `.bind::<dyn Iface, Impl>()`
Catalog::builder().add::<Impl>().build();

[0.7.2] - 2023-09-04

Changed

  • Fixed validation of Catalog self-injection

[0.7.1] - 2023-08-30

Changed

Added

[0.6.1] - 2023-06-15

Fixed

  • Account for overridden fields in generated builders when validating dependencies

[0.6.0] - 2023-06-05

Added

  • CatalogBuilder::add_builder() now accepts Arc<T> and Fn() -> Arc<T>
  • CatalogBuilder::add_factory() was replaced by CatalogBuilder::add_value_lazy() that accepts FnOnce() -> T and will cache result forever

[0.5.3] - 2023-06-05

Added

  • Deduplicating errors in ValidationError
  • CatalogBuilder::validate() now allows to specify types that are registered dynamically and should not be considered unresolved

Added

  • Keeping a CHANGELOG
