Cargo Features

[dependencies]
serde_json_borrow = { version = "0.7.1", default-features = false, features = ["cowkeys"] }
default = cowkeys

The cowkeys feature is set by default whenever serde_json_borrow is added without default-features = false somewhere in the dependency tree.

cowkeys default

Uses Cow<str> instead of &str. This enables support for escaped data in keys.
But it costs some deserialization performance.
