Cargo Features

[dependencies]
esplora-tapyrus = { version = "0.4.1", default-features = false, features = ["oldcpu", "rocksdb"] }
default = rocksdb

The rocksdb feature is set by default whenever esplora-tapyrus is added without default-features = false somewhere in the dependency tree.

oldcpu = rocksdb-oldcpu

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.
