Trait CategoryExt 

pub trait CategoryExt {
    type Ret;

    // Required method
    fn _internal_error_mut(self, f: impl FnOnce(&mut Error)) -> Self::Ret;

    // Provided methods
    fn with_category(self, category: Category) -> Self::Ret
       where Self: Sized { ... }
    fn bad_request(self) -> Self::Ret
       where Self: Sized { ... }
}

Convenience trait for easily adding categories to errors.

Required Associated Types

type Ret

The type that is returned from this trait’s functions.

Required Methods

fn _internal_error_mut(self, f: impl FnOnce(&mut Error)) -> Self::Ret

For internal use.

Provided Methods

fn with_category(self, category: Category) -> Self::Ret

where Self: Sized,

Convenience trait for easily adding categories to errors.

fn bad_request(self) -> Self::Ret

where Self: Sized,

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.
