=== Built-in Types ===
-The following types are built-in to the parser:
- 'str' - arbitrary UTF-8 string
- 'int' - 64-bit signed integer (although the C code may place further
- restrictions on acceptable range)
- 'number' - floating point number
- 'bool' - JSON value of true or false
- 'int8', 'int16', 'int32', 'int64' - like 'int', but enforce maximum
- bit size
- 'uint8', 'uint16', 'uint32', 'uint64' - unsigned counterparts
- 'size' - like 'uint64', but allows scaled suffix from command line
- visitor
+The following types are predefined, and map to C as follows:
+
+ Schema C JSON
+ str char * any JSON string, UTF-8
+ number double any JSON number
+ int int64_t a JSON number without fractional part
+ that fits into the C integer type
+ int8 int8_t likewise
+ int16 int16_t likewise
+ int32 int32_t likewise
+ int64 int64_t likewise
+ uint8 uint8_t likewise
+ uint16 uint16_t likewise
+ uint32 uint32_t likewise
+ uint64 uint64_t likewise
+ size uint64_t like uint64_t, except StringInputVisitor
+ accepts size suffixes
+ bool bool JSON true or false
