Trait AuthBackend 

pub trait AuthBackend: Send + Sync {
    // Required method
    fn verify<'life0, 'life1, 'async_trait>(
        &'life0 self,
        hash: &'life1 str,

Trait for authentication backends.

Implementations must be thread-safe (Send + Sync) as they may be called concurrently from multiple connections.

Required Methods

fn verify<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<AuthResult, AuthError>> + Send + 'async_trait>>

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

Verify a password hash.

Arguments

• hash - The SHA224 hex-encoded hash of the password

Returns

• Ok(AuthResult) - Authentication successful
• Err(AuthError) - Authentication failed

Provided Methods

fn record_traffic<'life0, 'life1, 'async_trait>( &'life0 self, _user_id: &'life1 str, _bytes: u64, ) -> Pin<Box<dyn Future<Output = Result<(), AuthError>> + Send + 'async_trait>>

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

Optional: Record traffic usage for a user.

Default implementation does nothing.

Implementations on Foreign Types

impl<A: AuthBackend + ?Sized> AuthBackend for Box<A>

Blanket implementation for Box<A> where A: AuthBackend.

fn verify<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<AuthResult, AuthError>> + Send + 'async_trait>>

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

fn record_traffic<'life0, 'life1, 'async_trait>( &'life0 self, user_id: &'life1 str, bytes: u64, ) -> Pin<Box<dyn Future<Output = Result<(), AuthError>> + Send + 'async_trait>>

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

impl<A: AuthBackend + ?Sized> AuthBackend for Arc<A>

Blanket implementation for Arc<A> where A: AuthBackend.

This allows passing Arc<AuthBackend> directly to functions expecting impl AuthBackend.

fn verify<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<AuthResult, AuthError>> + Send + 'async_trait>>

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

fn record_traffic<'life0, 'life1, 'async_trait>( &'life0 self, user_id: &'life1 str, bytes: u64, ) -> Pin<Box<dyn Future<Output = Result<(), AuthError>> + Send + 'async_trait>>

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