バイナリサイズ最適化

[riii111]

対象

1. image

サポートする機能を限定。例↓

[dependencies]
image = { version = "0.24", default-features = false, features = ["jpeg", "png", "gif"] }

2. mongodb

zstd圧縮やAWS認証を無効化。例↓

# After
mongodb = { version = "2.8", default-features = false, features = [
    "async-std-runtime",  # または "tokio-runtime"
    "bson-uuid-0_8",     # UUIDを使用する場合
    "bson-chrono-0_4"    # DateTimeを使用する場合
] }

3. aws-sdk-s3

基本的なS3操作のみとし、認証機能とかは削除

aws-sdk-s3 = { version = "0.28", default-features = false, features = [
    "rt-tokio",        # Tokioランタイムを使用
    "native-tls",      # TLS実装
    "behavior-version-latest"
] }

4. actix-web

以下みたいな感じで修正

actix-web = { version = "4.0", features = [
    "compress-brotli",    # 必要な圧縮アルゴリズム
    "compress-gzip",
    "cookies",            # クッキーを使用する場合
    "secure-cookies"      # セキュアクッキーを使用する場合
] }
