guardExceptionAsync<T extends Object?, E extends Exception> static method

Future<Result<T, E>> guardExceptionAsync<T extends Object?, E extends Exception>(Future<T> asyncBlock())

Executes an asynchronous function, catching only Exception types.

A convenience method that constrains the error type to Exception rather than accepting any Object. Use this when you want Error values to propagate uncaught.

Example:

final result = await Result<String, IOException>.guardExceptionAsync(
  () => file.readAsString(),
);

Implementation

static Future<Result<T, E>> guardExceptionAsync<
  T extends Object?,
  E extends Exception
>(Future<T> Function() asyncBlock) => guardAsync<T, E>(asyncBlock);
