Struct Config 

pub struct Config {
    pub write_level: Level,
    pub print_level: Level,
    pub directory: String,
    pub file_prefix: Option<String>,
    pub size_limit: Option<u64>,
    pub duration_limit: Option<u64>,
}

Configuration for the logger.

Fields

write_level: Level

The level that the logger will accept for writing to a file.

Default: Level::Info

print_level: Level

The level that the logger will accept for printing to the console.

Default: Level::Info

directory: String

The directory where the log files will be stored. The directory along with prefix will be used as a key for getting the writer. If 2 logger having same directory and file_prefix, the writer will be the same one regardless of if limits are different. This is to prevent multiple writers working on the same file.

Default: ./logs

file_prefix: Option<String>

The prefix of the log file. The log file will be named as {prefix} {date}_{time}.log. If the field is None, the log file will be named as {date}_{time}.log. Error of unable to create the log file with the unsupported character in prefix is not handled.

If one logger having no prefix, size_limit and duration_limit the file name will always be log.log.

Default: None

size_limit: Option<u64>

The size limit in bytes of the log file. When the file size exceeds this limit, the file will be rotated. If the 0 is set, the file will never be rotated by size.

Default: 10 * 1024 * 1024

duration_limit: Option<u64>

The duration limit in seconds of the log file. When the file duration exceeds this limit, the file will be rotated. If the 0 is set, the file will never be rotated by duration.
