Struct Async 

pub struct Async { /* private fields */ }

A composable appender, logging and flushing asynchronously.

Examples

use logforth_append_async::AsyncBuilder;
use logforth_core::append::Stderr;

let async_append = AsyncBuilder::new("logforth-async-append")
    .overflow_drop_incoming()
    // for demonstration purposes; in practice, this can be a file appender, etc.
    .append(Stderr::default())
    .build();

Caveats

The caller or application should ensure that the flush method is called before the program exits to write out any buffered events, especially when this appender is used in a global context.

The drop glue will also flush the appender. But, in Rust, static items do not call drop at the end of the program.

Trait Implementations

fn append( &self, record: &Record<'_>, diags: &[Box<dyn Diagnostic>], ) -> Result<(), Error>

Dispatch a log record to the append target.

fn flush(&self) -> Result<(), Error>

Flush any buffered records.

impl Debug for Async

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

Formats the value using the given formatter.
