[−][src]Struct xaynet_server::storage::traits::MaskScoreIncr
A wrapper that contains the result of the "increment mask score" operation.
Implementations
impl MaskScoreIncr
[src]
pub fn into_inner(self) -> Result<(), MaskScoreIncrError>
[src]
Unwraps this wrapper, returning the underlying result.
Methods from Deref<Target = Result<(), MaskScoreIncrError>>
#[must_use =
"if you intended to assert that this is ok, consider `.unwrap()` instead"]pub const fn is_ok(&self) -> bool
1.0.0 (const: 1.48.0)[src]
Returns true
if the result is Ok
.
Examples
Basic usage:
let x: Result<i32, &str> = Ok(-3); assert_eq!(x.is_ok(), true); let x: Result<i32, &str> = Err("Some error message"); assert_eq!(x.is_ok(), false);
#[must_use =
"if you intended to assert that this is err, consider `.unwrap_err()` instead"]pub const fn is_err(&self) -> bool
1.0.0 (const: 1.48.0)[src]
Returns true
if the result is Err
.
Examples
Basic usage:
let x: Result<i32, &str> = Ok(-3); assert_eq!(x.is_err(), false); let x: Result<i32, &str> = Err("Some error message"); assert_eq!(x.is_err(), true);
#[must_use]pub fn contains<U>(&self, x: &U) -> bool where
U: PartialEq<T>,
[src]
U: PartialEq<T>,
Returns true
if the result is an Ok
value containing the given value.
Examples
#![feature(option_result_contains)] let x: Result<u32, &str> = Ok(2); assert_eq!(x.contains(&2), true); let x: Result<u32, &str> = Ok(3); assert_eq!(x.contains(&2), false); let x: Result<u32, &str> = Err("Some error message"); assert_eq!(x.contains(&2), false);
#[must_use]pub fn contains_err<F>(&self, f: &F) -> bool where
F: PartialEq<E>,
[src]
F: PartialEq<E>,
Returns true
if the result is an Err
value containing the given value.
Examples
#![feature(result_contains_err)] let x: Result<u32, &str> = Ok(2); assert_eq!(x.contains_err(&"Some error message"), false); let x: Result<u32, &str> = Err("Some error message"); assert_eq!(x.contains_err(&"Some error message"), true); let x: Result<u32, &str> = Err("Some other error message"); assert_eq!(x.contains_err(&"Some error message"), false);
pub const fn as_ref(&self) -> Result<&T, &E>
1.0.0 (const: 1.48.0)[src]
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
Basic usage:
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"));
pub fn iter(&self) -> Iter<'_, T>
1.0.0[src]
Returns an iterator over the possibly contained value.
The iterator yields one value if the result is Result::Ok
, otherwise none.
Examples
Basic usage:
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);
pub fn as_deref(&self) -> Result<&<T as Deref>::Target, &E>
1.47.0[src]
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);
