Methods from Deref<Target = Result<Row, DataflowError>>§
1.0.0 · sourcepub fn as_ref(&self) -> Result<&T, &E>
pub fn as_ref(&self) -> Result<&T, &E>
Converts from &Result<T, E>
to Result<&T, &E>
.
Produces a new Result
, containing a reference
into the original, leaving the original in place.
§Examples
let x: Result<u32, &str> = Ok(2);
assert_eq!(x.as_ref(), Ok(&2));
let x: Result<u32, &str> = Err("Error");
assert_eq!(x.as_ref(), Err(&"Error"));
1.0.0 · sourcepub fn as_mut(&mut self) -> Result<&mut T, &mut E>
pub fn as_mut(&mut self) -> Result<&mut T, &mut E>
Converts from &mut Result<T, E>
to Result<&mut T, &mut E>
.
§Examples
fn mutate(r: &mut Result<i32, i32>) {
match r.as_mut() {
Ok(v) => *v = 42,
Err(e) => *e = 0,
}
}
let mut x: Result<i32, i32> = Ok(2);
mutate(&mut x);
assert_eq!(x.unwrap(), 42);
let mut x: Result<i32, i32> = Err(13);
mutate(&mut x);
assert_eq!(x.unwrap_err(), 0);
1.47.0 · sourcepub fn as_deref(&self) -> Result<&<T as Deref>::Target, &E>where
T: Deref,
pub fn as_deref(&self) -> Result<&<T as Deref>::Target, &E>where
T: Deref,
Converts from Result<T, E>
(or &Result<T, E>
) to Result<&<T as Deref>::Target, &E>
.
Coerces the Ok
variant of the original Result
via Deref
and returns the new Result
.
§Examples
let x: Result<String, u32> = Ok("hello".to_string());
let y: Result<&str, &u32> = Ok("hello");
assert_eq!(x.as_deref(), y);
let x: Result<String, u32> = Err(42);
let y: Result<&str, &u32> = Err(&42);
assert_eq!(x.as_deref(), y);
1.47.0 · sourcepub fn as_deref_mut(&mut self) -> Result<&mut <T as Deref>::Target, &mut E>where
T: DerefMut,
pub fn as_deref_mut(&mut self) -> Result<&mut <T as Deref>::Target, &mut E>where
T: DerefMut,
Converts from Result<T, E>
(or &mut Result<T, E>
) to Result<&mut <T as DerefMut>::Target, &mut E>
.
Coerces the Ok
variant of the original Result
via DerefMut
and returns the new Result
.
§Examples
let mut s = "HELLO".to_string();
let mut x: Result<String, u32> = Ok("hello".to_string());
let y: Result<&mut str, &mut u32> = Ok(&mut s);
assert_eq!(x.as_deref_mut().map(|x| { x.make_ascii_uppercase(); x }), y);
let mut i = 42;
let mut x: Result<String, u32> = Err(42);
let y: Result<&mut str, &mut u32> = Err(&mut i);
assert_eq!(x.as_deref_mut().map(|x| { x.make_ascii_uppercase(); x }), y);
1.0.0 · sourcepub fn iter(&self) -> Iter<'_, T>
pub fn iter(&self) -> Iter<'_, T>
Returns an iterator over the possibly contained value.
The iterator yields one value if the result is Result::Ok
, otherwise none.
§Examples
let x: Result<u32, &str> = Ok(7);
assert_eq!(x.iter().next(), Some(&7));
let x: Result<u32, &str> = Err("nothing!");
assert_eq!(x.iter().next(), None);
1.0.0 · sourcepub fn iter_mut(&mut self) -> IterMut<'_, T>
pub fn iter_mut(&mut self) -> IterMut<'_, T>
Returns a mutable iterator over the possibly contained value.
The iterator yields one value if the result is Result::Ok
, otherwise none.
§Examples
let mut x: Result<u32, &str> = Ok(7);
match x.iter_mut().next() {
Some(v) => *v = 40,
None => {},
}
assert_eq!(x, Ok(40));
let mut x: Result<u32, &str> = Err("nothing!");
assert_eq!(x.iter_mut().next(), None);
