Cargo Features

[dependencies]
alexa-verifier = { version = "0.2.1", default-features = false, features = ["sync", "async"] }
default = async, sync

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

sync default

Enables blocking of reqwest ^0.10.0-alpha.2

async default = futures-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.
