error_codes.md

Error codes in 0L has two components:

• The error reason
• The error category

Error Reason

The error reason has three components:

• The file prefix (the first character and a counter). e.g 1801 in Reconfigmodule. Refer to table below
• index of function (found in file). e.g. 06 for process_outgoing
• index of Assert in that function e.g. 02 for the second Transaction::Assert

For instance: Reconfig there could be a file prefix number e.g 1801 appended by an index for the function like e.g 06 for process_outgoing, then an index of all errors within that function, e.g. on the second assert 02. The corresponding error reason is 1801 & 06 & 02 === 18010602

File Prefix

The file prefix is based on first character and counter. Alphabet to number conversion: a=01, b=02, ... z=26. The next two digits form the counter, which starts at 0 and is incremented if two files have same first character.

The mapping of prefix is available in this table.
