Methods
-
andThen<U, F>(Result<U, F> f(T t))
→ Result<U, F>
-
Similar to
map Except you must return a new Result.
override
-
asyncAndThen<U, F>(ResultAsync<U?, F?> f(T t))
→ ResultAsync<U, F>
-
Similar to
map Except you must return a new Result.
override
-
asyncMap<U>(Future<U> f(T t))
→ ResultAsync<U, E>
-
Maps a
Result<T, E> to ResultAsync<U, E>
by applying an async function to a contained Ok value, leaving an Err
value untouched.
override
-
isErr()
→ bool
-
Used to check if a
Result is an Err
override
-
isOk()
→ bool
-
Used to check if a
Result is an OK
override
-
map<A>(A f(T t))
→ Result<A, E>
-
Maps a
Result<T, E> to Result<U, E>
by applying a function to a contained Ok value, leaving an Err value
untouched.
override
-
mapErr<U>(U f(E error))
→ Result<T, U>
-
Maps a
Result<T, E> to Result<T, F> by applying a function to a
contained Err value, leaving an Ok value untouched.
override
-
match<A>(A ok(T t), A err(E e))
→ A
-
Given 2 functions (one for the
Ok variant and one for the Err variant)
execute the function that matches the Result variant.
override
-
noSuchMethod(Invocation invocation)
→ dynamic
-
Invoked when a nonexistent method or property is accessed.
inherited
-
orElse<A>(Result<T, A> f(E error))
→ Result<T, A>
-
Takes an
Err value and maps it to a Result<T, SomeNewType>.
override
-
safeUnwrap()
→ Stream<T>
-
Emulates Rust's
? operator in safeTry's body. See also safeTry.
override
-
toString()
→ String
-
A string representation of this object.
inherited
-
unsafeUnwrap({ErrorConfig? config})
→ T
-
This method is unsafe, and should only be used in a test environments
override
-
unsafeUnwrapErr({ErrorConfig? config})
→ E
-
This method is unsafe, and should only be used in a test environments
override
-
unwrapOr(T v)
→ T
-
Unwrap the
Ok value, or return the default if there is an Err
