pub const PRIMITIVE_CONVERSION_TARGETS: &[&str];Expand description
The set of primitive type names that can appear as the callee of a
canonical primitive associated conversion (Prim.from(x) / Prim.try_from).
Restricted to the conversion targets the canonical matrix defines
(register_canonical_conversions): Int/Float (numeric widening +
TryFrom[String]), String (From[Char]). Sized primitives (Int64, …)
are conversion targets too, but are not in the resolver’s type-name vocab,
so they never reach codegen as an associated-call callee; Int/Float/
String are the v1-reachable callees.
