Cargo Features

[dependencies]
feignhttp = { version = "0.5.2", default-features = false, features = ["reqwest-client", "isahc-client", "json", "log"] }
default = reqwest-client

The reqwest-client feature is set by default whenever feignhttp is added without default-features = false somewhere in the dependency tree.

reqwest-client default = reqwest
isahc-client = isahc
json = serde_json

Enables json of isahc and reqwest ^0.11
