//! Experimental way to report program/SDK bugs
//!
//! This is mostly used instead of panics where appropriate (for example in
//! assertions), as panics are extremely costly in WebAssembly (i.e. we restart
//! the VM after panic occurs)

/// This errors means bug in SDK or environment running WebAssembly
#[derive(thiserror::Error, Debug)]
#[error("bug detected")]
