Constant const_sv2::NOISE_HASHED_PROTOCOL_NAME_CHACHA

pub const NOISE_HASHED_PROTOCOL_NAME_CHACHA: [u8; 32];

If protocolName is less than or equal to 32 bytes in length, use protocolName with zero bytes appended to make 32 bytes. Otherwise, apply HASH to it. For name = “Noise_NX_Secp256k1+EllSwift_ChaChaPoly_SHA256”, we need the hash.
