Struct MakeStderr 

Source 
pub struct MakeStderr;
Expand description

A MakeWriter that writes to stderr.

This is functionally the same as using std::io::stderr as a MakeWriter, except it has a named type and can therefore be used in type signatures.

fn with_max_level(self, level: Level) -> WithMaxLevel<Self>
where Self: Sized,

Wraps self and returns a MakeWriter that will only write output for events at or below the provided verbosity Level. For instance, Level::TRACE is considered to be _more verbosethanLevel::INFO`. Read more
