Cargo Features

[dependencies]
apollo-language-server = { version = "0.3.0", default-features = false, features = ["tokio", "wasm"] }
default = tokio

The tokio feature is set by default whenever apollo-language-server is added without default-features = false somewhere in the dependency tree.

tokio default

Enables tokio, runtime-tokio of tower-lsp

wasm = wasm-bindgen-futures

Enables wasm-bindgen of debounced, runtime-agnostic of tower-lsp

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.
