Trait OAuthRefreshTokenFormatter

    fn encrypt(

        token: &str,

Better Auth’s formatRefreshToken. Both callbacks are required by its types; absence of the whole formatter preserves raw refresh credentials.

Required Methods

fn encrypt( &self, token: &str, session_id: Option<&str>, ) -> AuthResult<OAuthRefreshTokenEncryption>

Invoked after refresh persistence (and rotation claim), before prefixing.

fn decrypt<'life0, 'life1, 'async_trait>( &'life0 self, token: &'life1 str, ) -> Pin<Box<dyn Future<Output = AuthResult<OAuthDecodedRefreshToken>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Invoked after removing the configured prefix; unlike encryption this is awaited.

Dyn Compatibility

This trait is dyn compatible.

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