Log line parser

Story

In this exercise you'll be processing log-lines.

Each log line is a string formatted as follows: "[<LVL>]: <MESSAGE>".

These are the different log levels:

• TRC (trace)
• DBG (debug)
• INF (info)
• WRN (warning)
• ERR (error)
• FTL (fatal)

Tasks

These are example tasks that fit the log line parser:

• Parse log level to enum
• Support unknown log levels
• Convert a log line to a different format with the log level converted to a numeric value

Implementations

• C#: logs-logs-logs (reference implementation)
• Rust: enums
• Python: log-levels
• Swift: enums
