Cargo Features

[dependencies]
http-range-client = { version = "0.8.0", default-features = false, features = ["reqwest-async", "reqwest-sync", "ureq-sync"] }
default = reqwest-async, reqwest-sync

These default features are set whenever http-range-client is added without default-features = false somewhere in the dependency tree.

reqwest-async default = reqwest
reqwest-sync default

Enables blocking of reqwest

ureq-sync = ureq

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.

reqwest reqwest-async reqwest-sync
ureq ureq-sync?
