//! This namespace is the default one used by the Zig compiler to emit various
|

//! kinds of safety panics, due to the logic in `std.builtin.Panic`.
|
|
//!
|
|
//! Since Zig does not have interfaces, this file serves as an example template
|
|
//! for users to provide their own alternative panic handling.
|
|
//!
|
|
//! As an alternative, see `std.debug.FormattedPanic`.
