Struct logosaurus::Logger

pub struct Logger { /* fields omitted */ }

Represents a logging object that writes to a specified output. It can be used simultaneously from multiple threads; it guarantees to serialize writes.

Use LoggerBuilder to construct a Logger, or use Logger::default().

Implementations

impl Logger

pub fn builder() -> LoggerBuilder

Returns a LoggerBuilder that can be used to build a Logger.

pub fn level(&self) -> LevelFilter

Returns the current level.

pub fn set_level(&mut self, level: LevelFilter)

Set the level.

pub fn out(&self) -> Arc<Mutex<Box<dyn Write + Send>>>

Returns the destination where output will be written.

pub fn set_out(&mut self, out: Box<dyn Write + Send>)

Set the destination to write output.

pub fn flags(&self) -> Flag

Returns the current formatting flags.

pub fn set_flags(&mut self, flag: Flag)

Set the formatting flags.

pub fn prefix(&self) -> &str

Returns the current ouput prefix.

pub fn set_prefix(&mut self, prefix: &str)

Set the output prefix.

pub fn write_output(
    &self,
    level: Level,
    target: &str,
    file: Option<&str>,
    line: Option<u32>,
    s: &str
)

Writes the given string s using the logger. Typically, you would not use this directly but instead use the macros provided by the log crate.

Trait Implementations

impl Default for Logger

fn default() -> Logger

Returns a default Logger.

A default Logger has

• level: log::LevelFilter::Trace,
• out: stderr,
• flags: L_STD, and
• prefix: "" (empty string)

impl Log for Logger

fn enabled(&self, metadata: &Metadata<'_>) -> bool

Determines if a log message with the specified metadata would be logged.

fn log(&self, record: &Record<'_>)

Logs the Record.
