Application-text-async-logger

ApplicationTextAsyncLogger is the application-facing async logger alias for text-console output. It currently maps directly to AsyncLogger[@bitlogger.FormattedConsoleSink] and keeps the same async lifecycle and queue helper surface while preserving the concrete text sink shape.

Interface

pub type ApplicationTextAsyncLogger = AsyncLogger[@bitlogger.FormattedConsoleSink]

output

• ApplicationTextAsyncLogger - Application-facing name for the text-console async logger shape.

Explanation

Detailed rules explaining key parameters and behaviors

• This alias does not introduce a new runtime type or wrapper layer.
• It preserves the same async lifecycle helpers as other async logger aliases.
• Because this is only an alias, methods that are async on AsyncLogger[@bitlogger.FormattedConsoleSink] remain async here as well.
• The alias therefore keeps the same text-console-specific builder and lifecycle semantics already documented on AsyncLogger[@bitlogger.FormattedConsoleSink], including the concrete sink shape and runtime-dependent close/failure behavior.
• The alias exists to give application code a clearer public name when it wants the concrete text-console sink shape explicitly.
• build_application_text_async_logger(...) returns this alias.

How to Use

Here are some specific examples provided.

When Need An App-level Name For Text-console Async Output

When application code wants a stable type name for a text-console async logger:

let logger : ApplicationTextAsyncLogger = build_application_text_async_logger(
  AsyncLoggerBuildConfig::new(logger=text_console(target="app.text.async")),
)

In this example, the application alias keeps the same underlying async logger behavior while preserving the text sink shape explicitly.

When Pass A Text-console Async Logger Through App-level APIs

When caller code should know it is working with the text-console variant:

async fn start_text_async(logger : ApplicationTextAsyncLogger) -> Unit {
  logger.run()
}

In this example, the app-facing alias communicates the concrete text-console async shape directly, while run() keeps its async calling contract.

Error Case

e.g.:

• Because this is only an alias, any async target limitations or runtime behavior still apply unchanged.

• If code does not need the concrete text-console sink shape, ApplicationAsyncLogger is the broader runtime-sink async alias.

Notes

1. This alias is about naming and public intent, not a different async implementation.

2. Use build_application_text_async_logger(...) when callers want the FormattedConsoleSink-backed async type explicitly.

3. Use ApplicationAsyncLogger when application code should keep the broader runtime-sink shape instead of the text-console-specific one.
