Required Methods

fn context(self, message: &'static str) -> Result<O, Error>

If the value is Err/None, add a simple context string onto an error, converting it to loga::Error in the process.

fn context_with( self, message: &'static str, attrs: impl Fn(&mut HashMap<&'static str, String>) ) -> Result<O, Error>

If the value is Err/None, add a simple context string and attributes pairs onto an error, converting it to loga::Error in the process.

fn log_context(self, log: &Log, message: &'static str) -> Result<O, Error>

If the value is Err/None, add attributes from the log as well as a simple context string to an error, converting it to loga::Error in the process.

fn log_context_with( self, log: &Log, message: &'static str, attrs: impl Fn(&mut HashMap<&'static str, String>) ) -> Result<O, Error>

If the value is Err/None, add attributes from the log as well as the specified attributes and a simple context string to an error, converting it to loga::Error in the process.

fn warn(self, log: &Log, message: &'static str)

fn warn_with( self, log: &Log, message: &'static str, attrs: impl Fn(&mut HashMap<&'static str, String>) )

Object Safety

This trait is not object safe.
