Structs

JSONLexerRange

struct JSONLexerRange(Input, LexOptions options = LexOptions.init, String = string)

* A lazy input range of JSON tokens. * * This range type takes an input string range and converts it into a range of * JSONToken values. * * See lexJSON for more information.

JSONNumber

struct JSONNumber

Represents a JSON number literal with lazy conversion.

JSONString

struct JSONString(String)

Represents a JSON string literal with lazy (un)escaping.

JSONToken

struct JSONToken(S)

* A low-level JSON token as returned by JSONLexer.
