Trait DecodingKeyFn 

pub trait DecodingKeyFn:
    Send
    + Sync
    + Clone {
    type Error: Error + Send;

    // Required method
    fn decoding_key<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<DecodingKey, Self::Error>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait to get a decoding key asynchronously

Required Associated Types

type Error: Error + Send

Required Methods

fn decoding_key<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<DecodingKey, Self::Error>> + Send + 'async_trait>>

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
