Trait TryFromInput

pub trait TryFromInput: Send + Sized {
    type Error: Error + Send;

    // Required method
    fn try_from_input(
        input: HandlerInput,
    ) -> impl Future<Output = Result<Option<Self>, Self::Error>> + Send;
}

Allows to create a specific handler input.

Required Associated Types

type Error: Error + Send

An error when conversion failed.

Required Methods

fn try_from_input( input: HandlerInput, ) -> impl Future<Output = Result<Option<Self>, Self::Error>> + Send

Performs conversion.

Arguments

• input - An input to convert from.

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.
