## Build-async-text-logger
|
|
|
|
Build an async logger directly from `AsyncLoggerBuildConfig`, but keep the concrete sink type as `FormattedConsoleSink` instead of the broader runtime sink wrapper. This helper is the text-console specific counterpart to `build_async_logger(...)`.
|
|
|
|
### Interface
|
|
|
|
```moonbit
|
|
pub fn build_async_text_logger(config : AsyncLoggerBuildConfig) -> AsyncLogger[@bitlogger.FormattedConsoleSink] {
|
|
```
|
|
|
|
#### input
|
|
|
|
- `config : AsyncLoggerBuildConfig` - Combined sync logger config plus async queue and flush config.
|
|
|
|
#### output
|
|
|
|
- `AsyncLogger[FormattedConsoleSink]` - Config-built async logger backed by a concrete text console sink.
|
|
|
|
### Explanation
|
|
|
|
Detailed rules explaining key parameters and behaviors
|
|
|
|
- This builder converts `config.logger.sink.text_formatter` into a runtime `TextFormatter` and wires it into `text_console_sink(...)`.
|
|
- The returned logger inherits `min_level`, `target`, and timestamp behavior from `config.logger`.
|
|
- This helper is best suited to text-console output paths where callers want the concrete formatted sink type instead of `RuntimeSink`.
|
|
|
|
### How to Use
|
|
|
|
Here are some specific examples provided.
|
|
|
|
#### When Need Config-built Async Text Console Output
|
|
|
|
When async queue behavior is config-driven and output should stay on text console formatting:
|
|
```moonbit
|
|
let logger = build_async_text_logger(
|
|
AsyncLoggerBuildConfig::new(
|
|
logger=text_console(target="async.text"),
|
|
async_config=AsyncLoggerConfig::new(max_pending=4),
|
|
),
|
|
)
|
|
```
|
|
|
|
In this example, the async logger is built around a text console sink rather than the generic runtime sink enum.
|
|
|
|
### Error Case
|
|
|
|
e.g.:
|
|
- If the logger config was not intended for text-console style output, the broader `build_async_logger(...)` path may be a better fit.
|
|
|
|
- If the logger is never `run()`, pending records still follow the normal async queue lifecycle rules.
|
|
|
|
### Notes
|
|
|
|
1. This API is narrower than `build_async_logger(...)` because it preserves a concrete text sink type.
|
|
|
|
2. It is the base builder used by the application and library async text facades.
