# Types

data Tokens k e #

A well-formed JSON token stream.

Note: `Lit` exists to make `Tokens` have only 6 constructors. This may or may not have impact on performance.

Since: 2.1.2.0

Constructors

TkLit !Lit k |
TkText !Text k |
TkNumber !Number k |
TkArrayOpen (TkArray k e) |
TkRecordOpen (TkRecord k e) |
TkErr e |
