Methods

ok<T2>(T2 f(T)) → Future<Result<T2>>

If result is Err then returns this Err as is. If result is Ok then returns result of call f(result.val). Result of call f() must be a value of type T2.

okAsync<T2>(Future<T2> f(T)) → Future<Result<T2>>

If result is Err then returns this Err as is. If result is Ok then returns result of call await f(result.val). Result of call f() must be a value of type T2.

onErr(dynamic f(Error)) → Future<Result<T>>

Calls f(result.err) with side effect if this result is Err. Anyway returns this result as is.

onOk(dynamic f(T)) → Future<Result<T>>

Calls f(result.val) with side effect if this result is Ok. Anyway returns this result as is.

onResult(dynamic f(Result<T>)) → Future<Result<T>>

Calls f(this) with side effect and return this as is.

or(T? f()) → Future<Result<T>>

If this result is Ok, then returns it as is. If this result is Err, then call result = f(). If result of call f() is null, then returns Err. If result of call f() is value , then return Ok(value). If call of f() throws exception, then returns Err.

orAsync(Future<T?> f()) → Future<Result<T>>

If this result is Ok, then returns it as is. If this result is Err, then call result = await f(). If result of call f() is null, then returns Err. If result of call f() is value, then return Ok(value). If call of f() throws exception, then returns Err.

pipe<T2>(dynamic f(T)) → Future<Result<T2>>

If result is Err then returns this Err as is. If result is Ok then returns result of call f(result.val). If result of call f() is null - returns Err('function returned null'). If result of call f() is Result - returns it as is. If call of f() throws exception, then returns Err.

pipeAsync<T2>(Future f(T)) → Future<Result<T2>>

If result is Err then returns this Err as is. If result is Ok then returns result of call await f(result.val). If result of call f() is null - returns Err('function returned null'). If result of call f() is Result - returns it as is. If call of f() throws exception, then returns Err.
