bmb-json — Fast JSON Parser
Zero-copy JSON parser and serializer compiled from BMB.
Installation
pip install bmb-json
Quick Start
import bmb_json
bmb_json.validate('{"name": "BMB"}') # True
bmb_json.get_string('{"name": "BMB"}', "name") # "BMB"
bmb_json.get_number('{"version": 97}', "version") # 97
bmb_json.array_len('[1, 2, 3]') # 3
bmb_json.array_get('[10, 20, 30]', 1) # '20'
bmb_json.stringify('{ "a" : 1 , "b" : [2,3] }') # '{"a":1,"b":[2,3]}'
bmb_json.get_type('{"a":1}') # 'object'
