Cargo Features

[dependencies]
async-speed-limit = { version = "0.4.2", default-features = false, features = ["standard-clock", "fused-future", "read-initializer", "futures-io", "tokio"] }
default = fused-future, futures-io, standard-clock

These default features are set whenever async-speed-limit is added without default-features = false somewhere in the dependency tree.

standard-clock default = futures-timer

Affects clock::StandardClock

fused-future default = futures-core
read-initializer

This feature has been deprecated. It is only kept for downstream compatibility.

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.

futures-timer standard-clock
futures-io default
futures-core fused-future
tokio implicit feature

Enables tokio

tokio:

An event-driven, non-blocking I/O platform for writing asynchronous I/O backed applications
