Module const_panic::fmt
source · Expand description
Formatting-related items
Panic formatting for custom types can be done in these ways (in increasing order of verbosity):
- Using the
PanicFmt
derive macro (requires the opt-in"derive"
feature) - Using the
impl_panicfmt
macro (requires the default-enabled"non_basic"
feature) - Using the
flatten_panicvals
macro (requires the default-enabled"non_basic"
feature) - Manually implementing the
PanicFmt
trait as described in its docs.
