default full? = default_no_backend, rustls_backend: Defaults with different backends
default_native_tls = default_no_backend, native_tls_backend
default_no_backend default default_native_tls? = builder, cache, chrono, client, framework, gateway, http, model, standard_framework, utils: Serenity requires a backend, this picks all default features without a backend.
builder default_no_backend model?: Enables builder structs to configure Discord HTTP requests. Without this feature, you have to construct JSON manually at some places.

Affects serenity::builder…
cache default_no_backend temp_cache? = dashmap, fxhash, parking_lot: Enables the cache, which stores the data received from Discord gateway to provide access to complete guild data, channels, users and more without needing HTTP requests.

Affects context::Context.cache, client::Client.cache, help_commands::has_all_requirements, help_commands::searched_lowercase, help_commands::create_customised_help_data, shard_manager::ShardManagerOptions.cache, shard_queuer::ShardQueuer.cache, shard_runner::ShardRunner.cache, shard_runner::ShardRunnerOptions.cache, http::CacheHttp.cache, serenity::cache, help_commands::with_embeds, help_commands::plain…
collector full? = gateway, model: Enables collectors, a utility feature that lets you await interaction events in code with zero setup, without needing to setup an InteractionCreate event listener.

Affects serenity::collector, quick_modal::QuickModalResponse, quick_modal::CreateQuickModal…
client default_no_backend framework? voice? = http, typemap_rev: Wraps the gateway and http functionality into a single interface TODO: should this require "gateway"?

Affects serenity::client…
framework default_no_backend standard_framework? = client, model, utils: Enables the Framework trait which is an abstraction for old-style text commands.

Affects shard_manager::ShardManagerOptions.framework, shard_queuer::ShardQueuer.framework, shard_runner::ShardRunnerOptions.framework, serenity::framework…
gateway collector? default_no_backend = flate2: Enables gateway support, which allows bots to listen for Discord events.

Affects client::ClientBuilder, client::Client, serenity::gateway…
http client? default_no_backend model? = mime_guess, percent-encoding: Enables HTTP, which enables bots to execute actions on Discord.

Affects builder::Builder, tokio::spawn_named, serenity::http, help_commands::with_embeds, help_commands::plain…
model collector? default_no_backend framework? voice? = builder, http, utils: Enables wrapper methods around HTTP requests on model types.
Requires "builder" to configure the requests and "http" to execute them.
Note: the model type definitions themselves are always active, regardless of this feature.
TODO: remove dependeny on utils feature

Affects channel_id::MessagesIter, channel::AttachmentType, guild_id::MembersIter, mention::MentionParseError, misc::EmojiIdentifierParseError…
voice_model full? = serenity-voice-model
standard_framework default_no_backend = command_attr, framework, levenshtein, parking_lot, static_assertions, uwl: Affects framework::standard…
unstable_discord_api full?: Enables support for Discord API functionality that's not stable yet, as well as serenity APIs that are allowed to change even in semver non-breaking updates.

Affects gateway::Activity.sync_id, gateway::Activity.session_id…
utils default_no_backend framework? model?: Enables some utility functions that can be useful for bot creators.

Affects serenity::utils, mention::MentionParseError, misc::EmojiIdentifierParseError…
voice full? = client, model: Affects client::Client.voice_manager, shard_manager::ShardManagerOptions.voice_manager, shard_queuer::ShardQueuer.voice_manager, shard_runner::ShardRunnerOptions.voice_manager…
tokio_task_builder: Enables unstable tokio features to give explicit names to internally spawned tokio tasks

Enables tracing of tokio
interactions_endpoint full? = ed25519-dalek: Affects serenity::interactions_endpoint…
chrono default_no_backend: Uses chrono for Timestamp, instead of time

Enables chrono, chrono of optional typesize
full = collector, default, interactions_endpoint, unstable_discord_api, voice, voice_model: This enables all parts of the serenity codebase
(Note: all feature-gated APIs to be documented should have their features listed here!)
simd_json = simd-json: Enables simd accelerated parsing.

Enables simd_json of optional typesize
temp_cache = cache, mini-moka: Enables temporary caching in functions that retrieve data via the HTTP API.

Enables mini_moka of optional typesize
absolute_ratelimits: Removed feature (https://github.com/serenity-rs/serenity/pull/2246)
rustls_backend default = bytes: Backends to pick from:
- Rustls Backends

Enables rustls-tls of reqwest ^0.11.22, rustls-tls-webpki-roots of tokio-tungstenite ^0.21.0
native_tls_backend default_native_tls? = bytes: - Native TLS Backends

Enables native-tls of reqwest ^0.11.22 and tokio-tungstenite ^0.21.0

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

fxhash cache?

Enables fxhash
