Trait Encryptor 

pub trait Encryptor: Send + Sync {
    // Required methods
    fn encrypt(&self, plaintext: &[u8]) -> Result<Vec<u8>, Error>;
    fn describe(&self) -> String;
}

Available on crate feature decrypt only.

Turns configuration text into the bytes of an encrypted file.

The other direction from Decryptor, and deliberately not installed process-wide: who may read a file this program writes is a decision about that write, not a property of the process. It is passed to save_encrypted at the call site, where somebody can see which recipients they chose.

Required Methods

fn encrypt(&self, plaintext: &[u8]) -> Result<Vec<u8>, Error>

Encrypts plaintext into the bytes to write.

Errors

Whatever going wrong looks like for this scheme. Use Error::decrypt, which covers both directions.

fn describe(&self) -> String

How to name this encryptor in an error.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
