Cargo Features

[dependencies]
tracing-futures = { version = "0.2.5", default-features = false, features = ["std", "futures-01", "futures-03", "std-future", "tokio-executor", "tokio"] }

default = std, std-future

These default features are set whenever tracing-futures is added without default-features = false somewhere in the dependency tree.

std default futures-01? futures-03?

Enables std of tracing

Affects tracing-futures::WithSubscriber, tracing-futures::WithDispatch…

futures-01 = futures_01, std

futures-03 = futures, futures-task, std, std-future

std-future default futures-03? = pin-project
