Types

data Tokens k e Source #

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
