Methods from Deref<Target = Result<Entry, LoadingError>>
#[must_use]
pub fn is_ok(&self) -> bool
1.0.0[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]
pub fn is_err(&self) -> bool
1.0.0[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);
pub fn as_ref(&self) -> Result<&T, &E>
1.0.0[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 deref_ok(&self) -> Result<&<T as Deref>::Target, &E>
[src]
🔬 This is a nightly-only experimental API. (inner_deref
)
newly added
Converts from &Result<T, E>
to Result<&T::Target, &E>
.
Leaves the original Result in-place, creating a new one with a reference
to the original one, additionally coercing the Ok
arm of the Result via
Deref
.

)
newly added
Converts from &Result<T, E>
to Result<&T::Target, &E::Target>
.
Leaves the original Result in-place, creating a new one with a reference
to the original one, additionally coercing both the Ok
and Err
arms
of the Result via Deref
.
