Build-library-async-text-logger

Build a LibraryAsyncLogger[FormattedConsoleSink] from AsyncLoggerBuildConfig. This facade is the library-oriented async builder for text-console runtime output.

Interface

pub fn build_library_async_text_logger(
  config : AsyncLoggerBuildConfig,
) -> LibraryAsyncLogger[FormattedConsoleSink] {

input

• config : AsyncLoggerBuildConfig - Combined sync logger config and async queue/runtime config.

output

• LibraryAsyncLogger[FormattedConsoleSink] - Library-facing async logger backed by formatted console output.

Explanation

Detailed rules explaining key parameters and behaviors

• This API delegates to build_async_text_logger(...) and then wraps the result as LibraryAsyncLogger.
• It is useful when library code wants a narrow async facade while preserving a concrete text-console sink type.
• to_async_logger() can recover the underlying full async logger if needed.

How to Use

Here are some specific examples provided.

When Need A Narrow Async Text Logger For Libraries

When a library wants text-console async output and a narrower public type:

let logger = build_library_async_text_logger(
  AsyncLoggerBuildConfig::new(
    logger=text_console(target="lib.text.async"),
    async_config=AsyncLoggerConfig::new(max_pending=4),
  ),
)

In this example, the async text sink shape is preserved under the library facade.

Error Case

e.g.:

• If the embedded logger config does not describe text-console output, the caller should use the broader async facade instead.

• Normal async lifecycle expectations still apply if the logger is never run.

Notes

1. This is the library-side counterpart to build_application_text_async_logger(...).

2. It is most useful when a concrete text-console async sink type matters to the caller boundary.
