Struct PanicMessage

1.81.0 · Source

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

Expand description

A message that was given to the panic!() macro.

The Display implementation of this type will format the message with the arguments that were given to the panic!() macro.

See PanicInfo::message.

Implementations§

Source §

impl<'a> PanicMessage<'a>

1.81.0 (const: 1.84.0) · Source

pub const fn as_str(&self) -> Option<&'static str>

Gets the formatted message, if it has no arguments to be formatted at runtime.

This can be used to avoid allocations in some cases.

§Guarantees

For panic!("just a literal"), this function is guaranteed to return Some("just a literal").

For most cases with placeholders, this function will return None.

See fmt::Arguments::as_str for details.

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<A> DynCastExt for A

Source §

fn dyn_cast<T>( self, ) -> Result<<A as DynCastExtHelper<T>>::Target, <A as DynCastExtHelper<T>>::Source>
where A: DynCastExtHelper<T>, T: ?Sized,

Use this to cast from one trait object type to another. Read more

Source §

fn dyn_upcast<T>(self) -> <A as DynCastExtAdvHelper<T, T>>::Target
where A: DynCastExtAdvHelper<T, T, Source = <A as DynCastExtAdvHelper<T, T>>::Target>, T: ?Sized,

Use this to upcast a trait to one of its supertraits. Read more

Source §

fn dyn_cast_adv<F, T>( self, ) -> Result<<A as DynCastExtAdvHelper<F, T>>::Target, <A as DynCastExtAdvHelper<F, T>>::Source>
where A: DynCastExtAdvHelper<F, T>, F: ?Sized, T: ?Sized,

Use this to cast from one trait object type to another. This method is more customizable than the dyn_cast method. Here you can also specify the “source” trait from which the cast is defined. This can for example allow using casts from a supertrait of the current trait object. Read more

Source §

fn dyn_cast_with_config<C>( self, ) -> Result<<A as DynCastExtAdvHelper<<C as DynCastConfig>::Source, <C as DynCastConfig>::Target>>::Target, <A as DynCastExtAdvHelper<<C as DynCastConfig>::Source, <C as DynCastConfig>::Target>>::Source>
where C: DynCastConfig, A: DynCastExtAdvHelper<<C as DynCastConfig>::Source, <C as DynCastConfig>::Target>,

Use this to cast from one trait object type to another. With this method the type parameter is a config type that uniquely specifies which cast should be preformed. Read more
