.parse_max_memory(value) ⇒ Float?

Parse a max memory value into a number of bytes. The value can be a plain number of bytes or a number suffixed with "m" for megabytes or "g" for gigabytes (case insensitive).

Parameters:

  • value (String, nil) —

    The value to parse.

Returns:

  • (Float, nil) —

    The number of bytes or nil if the value is blank.

Raises:

  • (ArgumentError) —

    If the value cannot be parsed.
