Struct Builder

pub struct Builder { /* private fields */ }

Builder is a struct that holds the configuration for the logger.

The level field is the minimum log level that will be logged. The log_file field is the name of the log file. The log_file_max field is the maximum size of the log file in megabytes. The use_console field is a boolean that indicates whether or not to log to the console. The use_async field is a boolean that indicates whether or not to use an asynchronous logger.

The new() method

Properties:

• level: The log level to use.
• log_file: The name of the log file.
• log_file_max: The maximum number of log files to keep.
• use_console: If true, the logger will log to the console.
• use_async: Whether to use the async logger or not.
• filter: Use user-defined log filtering functions.
• plugin: Use a user-defined log output plug-in.

Examples

asnyclog::Builder::new()
    .level(log::LevelFilter::Debug)
    .log_file(String::from("./app.log"))
    .log_file_max(1024 * 1024)
    .use_console(true)
    .use_async(true)
    .filter(|r: &log::Record| r.target() != "gensql::sql_builder" || r.line().unwrap_or(0) != 72)
    .builder()?;
