Trait AnyError 

pub trait AnyError:
    Error
    + Any
    + Send
    + Sync {
    // Required method
    fn as_any(&self) -> &dyn Any;
}

The global, dowcastable any Error trait of the library.

This trait is used instead of [Error] when an error that is not known at compilation time cannot be placed in a generic due to object-safe trait constraint. The main use case is for backend features.

Required Methods

fn as_any(&self) -> &dyn Any

Dyn Compatibility

This trait is dyn compatible.

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