Expand description
A marker trait meant for use as the A
parameter in TypeMap
.
This can be used to construct TypeMap
s containing only types which
implement Debug
like so: TypeMap::<DebugAny>::custom()
, which produces
a TypeMap<DebugAny>
. Combine DebugAny
with Send
or Sync
to add
additional bounds.
There is also an exported alias for this type of TypeMap
, DebugMap
.
