Trait HasErrorCause 

pub trait HasErrorCause {
    type ReturnOperand<C>
       where C: Error + 'static,
             Self: Apply<HasErrorCauseOperation<C>>;

    // Required method
    fn has_cause<C>(&self) -> Self::ReturnOperand<C>
       where C: Error + 'static,
             Self: Apply<HasErrorCauseOperation<C>>;
}

Required Associated Types

type ReturnOperand<C> where C: Error + 'static, Self: Apply<HasErrorCauseOperation<C>>

Required Methods

fn has_cause<C>(&self) -> Self::ReturnOperand<C>

where C: Error + 'static, Self: Apply<HasErrorCauseOperation<C>>,

Dyn Compatibility

This trait is dyn compatible.

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