Trait PanicInfoExt

pub trait PanicInfoExt<'a> {
    // Required method
    fn panic_message(&'a self) -> impl Message + 'a;

    // Provided method
    fn panic_details(&'a self) -> PanicDetails<'a, impl Message + 'a> { ... }
}

Extension trait to provide better API for PanicInfo

Required Methods

fn panic_message(&'a self) -> impl Message + 'a

Retrieves underlying panic message

Provided Methods

fn panic_details(&'a self) -> PanicDetails<'a, impl Message + 'a>

Access uniform details of panic

Default implementation uses location of this function call. When panic location is known, it is overridden with specialized version

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.
