Expand description

Represents the ability to send logging messages to some kind of output, which is dictated by the required implementation of ILogger::write_line().

Required Methods§

source

fn write_line(&mut self, loglevel: &str, message: &str)

Send a formatted line to the logger. Must be implemented by any struct implementing the ILogger trait.

Parameters

  • loglevel

    Level of logging (“TRACE”, “INFO”, “ERROR”)

  • message

    Message to log

Provided Methods§

source

fn log_trace(&mut self, message: &str)

Log trace messages to the configured output. A newline will always be added to the message when writing to the log. Default behavior is to send the message to ILogger::write_line().

Parameters

  • message

    The message to write to the log.

source

fn log_info(&mut self, message: &str)

Log information messages to the configured output. A newline will always be added to the message when writing to the log. Default behavior is to send the message to ILogger::write_line().

Parameters

  • message

    The message to write to the log.

source

fn log_error(&mut self, message: &str)

Log error messages to the configured output. A newline will always be added to the message when writing to the log. Default behavior is to send the message to ILogger::write_line().

Parameters

  • message

    The message to write to the log.
