method Task.prototype.tryMap



Task.prototype.tryMap<U,

errFn: (error: unknown,
value: T,
) => Promisable<F>,
): Task<U, E | F>

Maps successful values with fn and transforms errors with errFn. Both receive the original value so you can contextualize the mapping.

errFn: (error: unknown,
value: T,
) => Promisable<F>

Task<U, E | F>
