macro_rules! gpu_err {
($($arg:tt)*) => { ... };
}Expand description
Build a GpuError::DriverCallFailed { reason: format!(...) } value.
Collapses the ubiquitous
GpuError::DriverCallFailed { reason: format!("...: {err}") }
struct literal into a single call. The macro forwards every argument
to format!, so callers retain full control over the message body,
including positional / named captures and interpolation of the
per-site err binding.
