Struct SimpleLogger

pub struct SimpleLogger { /* private fields */ }

Use the SimpleLogger struct to initialize a logger. From then on, the rust log framework should be used to output log statements as usual.

Example

use log::{info, error};
use simplog::SimpleLogger;

SimpleLogger::init(None); // Log level defaults to `Error`
info!("Hello World!");
// Produces nothing
error!("Goodbye World!");
// Produces "Goodbye World"

Implementations

impl SimpleLogger

pub fn init(verbosity: Option<&str>)

Initialize the logger, with an optionally provided log level (verbosity) in a &str If None is provided -> The log level will be set to Error If ‘Some(`verbosity’) is a &str with a valid log level, the string will be parsed and if valid set as the log level.

Example

use log::info;
use simplog::SimpleLogger;

SimpleLogger::init(Some("info"));
info!("Hello World!");
// Produces "Hello World"

pub fn init_prefix(verbosity: Option<&str>, prefix: bool)

Initialize the logger, with an optionally provided log level (verbosity) in a &str The default log level is Error if None is provided. prefix determines whether each log line output is prefixed with the level that produced it

Example

use log::info;
use simplog::SimpleLogger;

SimpleLogger::init_prefix(Some("info"), true);
info!("Hello World!");
// Produces "INFO   - Hello World"

pub fn init_prefix_timestamp( verbosity: Option<&str>, prefix: bool, timestamp: bool, )

Initialize the logger, with an optionally provided log level (verbosity) in a &str The default log level is Error if None is provided. prefix determines whether each log line output is prefixed with the level that produced it if timestamp is true, each log line will be prefixed with the elapsed time since the logger was initialized

Example

use log::info;
use simplog::SimpleLogger;

let mut logger = SimpleLogger::init_prefix_timestamp(Some("info"), false, true);
info!("Hello World!");
// Produces "1.246717ms   Hello World"
