Type conversions

Here's a table to visualize the type conversions in the Rell backend to its corresponding GTV types when inserting into and querying them.

Rell type	Operation input	Query input	Query output
entity	GtvInteger	GtvInteger	GtvInteger
enum	GtvInteger	GtvInteger (can be GtvString)	GtvInteger
struct	GtvArray	GtvArray (can be GtvDict)	GtvDict
integer	GtvInteger	GtvInteger	GtvInteger
big_integer	GtvBigInteger	GtvBigInteger	GtvBigInteger
decimal	GtvString	GtvString	GtvString
boolean	GtvInteger	GtvInteger	GtvInteger
rowid	GtvInteger	GtvInteger	GtvInteger
json	GtvString	GtvString	GtvString
text	GtvString	GtvString	GtvString
byte_array	GtvByteArray	GtvByteArray	GtvByteArray
nullable	GtvNull or type	GtvNull or type	GtvNull or type
collection	GtvArray	GtvArray	GtvArray
text map	GtvDict	GtvDict	GtvDict
non-text map (e.g., [[k1, v1], [k2, v2], ...])	GtvArray	GtvArray	GtvArray
named tuple (e.g., (x = 1, y = 2, z = 3))	GtvDict	GtvDict	GtvDict
unnamed tuple (e.g., (1, 2, 3))	GtvArray	GtvArray	GtvArray

Strict Type Conversion

Since Rell Version 0.13.9 the default behaviour of gtv type conversion have changed, from non-strict to strict. The following table highlights how this affects how operation arguments gets parsed.

Operation Input Rell Type	Types Accepted in Strict	Types Accepted in Non-Strict
byte_array	GtvByteArray	GtvByteArray
		GtvString
integer	GtvInteger	GtvInteger
		GtvBigInteger
big_integer	GtvBigInteger	GtvBigInteger
		GtvInteger
decimal	GtvString	GtvString
		GtvInteger
		GtvBigInteger
rowid	GtvInteger	GtvInteger
		GtvBigInteger
