func symbolName[T: enum](a: T): string

Returns the symbol name of an enum.

This uses symbolRank.

Example:

type B = enum
  b0 = (10, "kb0")
  b1 = "kb1"
  b2
let b = B.low
assert b.symbolName == "b0"
assert $b == "kb0"
static: assert B.high.symbolName == "b2"
type C = enum # HoleyEnum
  c0 = -3
  c1 = 4
  c2 = 20
assert c1.symbolName == "c1"

Iterators

iterator items[T: HoleyEnum](E: typedesc[T]): T: Iterates over an enum with holes.
Example:

type A = enum a0 = 2 a1 = 4 a2 B[T] = enum b0 = 2 b1 = 4 from std/sequtils import toSeq assert A.toSeq == [a0, a1, a2] assert B[float].toSeq == [B[float].b0, B[float].b1]

Templates

template symbolRank[T: enum](a: T): int

Returns the index in which a is listed in T.

The cost for a HoleyEnum is implementation defined, currently optimized for small enums, otherwise is O(T.enumLen).
