Methods

and<U>(Result<U, E> res) → Result<U, E>
Returns res if the result is Ok, otherwise returns the Err value of this.
inherited
andThen<U>(Result<U, E> op(T value)) → Result<U, E>
Calls op if the result is Ok, otherwise returns the Err value of this.
inherited
err() → E?
Converts from Result<T, E> to E?.
inherited
errOpt() → Option<E>
Converts from Result<T, E> to Option<E>.
inherited
expect(String msg) → T
Returns the contained Ok value, consuming the this value.
inherited
expectErr(String msg) → E
Returns the contained Err value, consuming the this value.
inherited
iter() → Iterable<T>
Returns an iterable over the possibly contained value.
inherited
map<U>(U op(T value)) → Result<U, E>
Maps a Result<T, E> to Result<U, E> by applying a function to a contained Ok value, leaving an Err value untouched.
inherited
mapErr<F>(F op(E err)) → Result<T, F>
Maps a Result<T, E> to Result<T, F> by applying a function to a contained Err value, leaving an Ok value untouched.
inherited
mapOr<U>(U defaultValue, U f(T value)) → U
Returns the provided default (if Err), or applies a function to the contained value (if Ok),
inherited
mapOrElse<U>(U defaultF(E err), U f(T value)) → U
Maps a Result<T, E> to U by applying fallback function defaultF to a contained Err value, or function f to a contained Ok value.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
ok() → T?
Converts from Result<T, E> to T?.
inherited
okOpt() → Option<T>
Converts from Result<T, E> to Option<T>.
inherited
or<F>(Result<T, F> res) → Result<T, F>
Returns res if the result is Err, otherwise returns the Ok value of this.
inherited
orElse<F>(Result<T, F> op(E err)) → Result<T, F>
Calls op if the result is Err, otherwise returns the Ok value of this.
inherited
toString() → String
A string representation of this object.
override
unwrap() → T
Returns the contained Ok value, consuming the this value.
inherited
unwrapErr() → E
Returns the contained Err value, consuming the this value.
inherited
unwrapOr(T defaultValue) → T
Returns the contained Ok value or a provided default.
inherited
unwrapOrElse(T op(E err)) → T
Returns the contained Ok value or computes it from a closure.
