1.10.0[−][src]Struct std::panic::PanicInfo
A struct providing information about a panic.
PanicInfo structure is passed to a panic hook set by the set_hook
function.
Examples
ⓘThis example panics
use std::panic; panic::set_hook(Box::new(|panic_info| { if let Some(s) = panic_info.payload().downcast_ref::<&str>() { println!("panic occurred: {:?}", s); } else { println!("panic occurred"); } })); panic!("Normal panic");Run
Implementations
impl<'a> PanicInfo<'a>[src]
pub fn payload(&self) -> &(dyn Any + 'static + Send)[src]
Returns the payload associated with the panic.
This will commonly, but not always, be a &'static str or String.
Examples
ⓘThis example panics
use std::panic; panic::set_hook(Box::new(|panic_info| { if let Some(s) = panic_info.payload().downcast_ref::<&str>() { println!("panic occurred: {:?}", s); } else { println!("panic occurred"); } })); panic!("Normal panic");Run
pub fn message(&self) -> Option<&Arguments<'_>>[src]
If the panic! macro from the core crate (not from std)
was used with a formatting string and some additional arguments,
returns that message ready to be used for example with fmt::write
pub fn location(&self) -> Option<&Location<'_>>[src]
Returns information about the location from which the panic originated, if available.
This method will currently always return Some, but this may change
in future versions.
Examples
ⓘThis example panics
use std::panic; panic::set_hook(Box::new(|panic_info| { if let Some(location) = panic_info.location() { println!("panic occurred in file '{}' at line {}", location.file(), location.line(), ); } else { println!("panic occurred but can't get location information..."); } })); panic!("Normal panic");Run
