Module toml
ballerina/toml Ballerina library
0.4.0
Overview
This module provides APIs to convert a TOML configuration file to map<json>, and vice-versa.
Since the parser is following LL(1) grammar, it follows a non-recursive predictive parsing algorithm which operates in a linear time complexity.
For information on the operations, which you can perform with the toml module, see the below Functions.
