Struct `PanicMessage`

struct PanicMessage<'a> { ... }

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

`impl<'a> PanicMessage<'a>`

const fn as_str(self: &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.
