 //! - `["rand"]` - Used to generate pseudo-random numbers. Uses [rand_chacha] and [rand_core].
-//! - `["ecc-secp256k1"]` - Contains types and methods for working with secp256k1 keys and signatures, 
+//! - `["ecc-secp256k1"]` - Contains types and methods for working with secp256k1 keys and signatures,
 //! as well as standard constants for key sizes. Uses [secp256k1](https://crates.io/crates/secp256k1).
