Struct orkhon::prelude::ops::nn::tract_downcast_rs::__std::panic::PanicInfo 1.10.0[−][src]
A struct providing information about a panic.
PanicInfo
structure is passed to a panic hook set by the set_hook
function.
Examples
ⓘ
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");
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
ⓘ
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");
pub fn message(&self) -> Option<&Arguments<'_>>
[src]
🔬 This is a nightly-only experimental API. (
panic_info_message
)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
ⓘ
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");
