stringviews

nimony/src/lib/stringviews.nim

• type pchar = ptr UncheckedArray[char]

• type StringView = object
    p: ptr UncheckedArray[char]
    len: int64

• template [](s: StringView; i: int64): char
• proc ==(a: StringView; b: StringView): bool
• proc ==(a: StringView; b: string): bool
• proc startsWith(s: StringView; prefix: string): bool
• proc add(s: var string; b: StringView)
• proc $(s: StringView): string
• proc toStringViewUnsafe(s: string): StringView

  Watch out that the string lives longer than the string view!

• proc hash(a: StringView): uint64
