Struct TestConsoleAppender 

pub struct TestConsoleAppender { /* private fields */ }

An appender that uses print! internally. This is less performant than a normal ConsoleAppender, but ensures output gets captured by the standard test harness.

Implementations

impl TestConsoleAppender

pub fn new(encoder: Box<dyn Encode>) -> Self

Create a new TestConsoleAppender with the given encoder.

pub fn make_config<'a, 'b>( targets: impl IntoIterator<Item = &'a str>, level: impl Into<Option<LevelFilter>>, pattern: impl Into<Option<&'b str>>, ) -> Config

Construct a sensible Config using a TestConsoleAppender and PatternEncoder.

If targets is empty, the root logger will be enabled at the given level. If targets is non-empty, the root logger will be disabled and all the given targets enabled at the given level.

Defaults:

• level = LevelFilter::Trace
• pattern = "{l} {M}::{L} {m}{n}"

Duplicate entries in targets are not allowed and will panic.
