## 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
|
|
|
|
```moonbit
|
|
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.
|
|
- 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:
|
|
```moonbit
|
|
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:
|
|
```moonbit
|
|
fn start_text_async(logger : ApplicationTextAsyncLogger) -> Unit {
|
|
logger.run()
|
|
}
|
|
```
|
|
|
|
In this example, the app-facing alias communicates the concrete text-console async shape directly.
|
|
|
|
### 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.
