Struct RustLogAdapter 

#[non_exhaustive]
pub struct RustLogAdapter;

This is an implementation of LoggerImpl that can be used to pipe CRT log messages into the Rust log facade. To install it, call RustLogAdapter::try_init(), and then CRT log messages will be sent to the log facade. These messages will follow that facade’s logic for when to emit log messages. All CRT log messages will have a target that starts with the value of AWSCRT_LOG_TARGET.

Implementations

impl RustLogAdapter

pub fn try_init() -> Result<(), LoggerInitError>

Try to install the log adapter as the current CRT logger. Only one CRT logger can be installed for the lifetime of the program, so this returns Err if a logger has already been installed.

Trait Implementations

impl Debug for RustLogAdapter

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl LoggerImpl for RustLogAdapter

fn log(&self, log_level: Level, subject: Subject, message: &str)

Log a new message at the given level for a subject

fn get_log_level(&self, _subject: Subject) -> Level

Get the maximum log level that this logger is currently interested in. This method allows the CRT to avoid the cost of formatting log messages that won’t be emitted.

fn set_log_level(&self, _level: Level) -> Result<(), Box<dyn Error>>

Set the maximum log level that this logger should be interested in.

fn clean_up(&self)

Clean up this logger. Called when the logger is being uninstalled. It will not receive any further calls after this one.
