Struct PanicInfo

pub struct PanicInfo<'a> { /* private fields */ }

A struct providing information about a panic.

A PanicInfo structure is passed to the panic handler defined by #[panic_handler].

Implementations

impl<'a> PanicInfo<'a>

pub fn message(&self) -> PanicMessage<'_>

The message that was given to the panic! macro.

Example

The type returned by this method implements Display, so it can be passed directly to write!() and similar macros.

#[panic_handler]
fn panic_handler(panic_info: &PanicInfo<'_>) -> ! {
    write!(DEBUG_OUTPUT, "panicked: {}", panic_info.message());
