Cargo Features
multer has no features set by default.
[dependencies]
multer = { version = "3.0.0", features = ["all", "json", "tokio-io"] }- all = json
- json all? = serde, serde_json
- tokio-io = tokio, tokio-util
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.
