Enum retry::OperationResult
source · [−]pub enum OperationResult<T, E> {
Ok(T),
Retry(E),
Err(E),
}
Expand description
A result that represents either success, retryable failure, or immediately-returning failure.
Variants
Ok(T)
Contains the success value.
Retry(E)
Contains the error value if duration is exceeded.
Err(E)
Contains an error value to return immediately.
Implementations
sourceimpl<T, E> OperationResult<T, E>
impl<T, E> OperationResult<T, E>
sourcepub fn is_ok(&self) -> bool
pub fn is_ok(&self) -> bool
Returns true
if the result is OperationResult::Ok
.
Examples
Basic usage:
let x: OperationResult<i32, &str> = OperationResult::Ok(-3);
assert_eq!(x.is_ok(), true);
let x: OperationResult<i32, &str> = OperationResult::Retry("Some error message");
assert_eq!(x.is_ok(), false);
let x: OperationResult<i32, &str> = OperationResult::Err("Some other error message");
assert_eq!(x.is_ok(), false);
sourcepub fn is_retry(&self) -> bool
pub fn is_retry(&self) -> bool
Returns true
if the result is OperationResult::Retry
.
Examples
Basic usage:
let x: OperationResult<i32, &str> = OperationResult::Ok(-3);
assert_eq!(x.is_retry(), false);
let x: OperationResult<i32, &str> = OperationResult::Retry("Some error message");
assert_eq!(x.is_retry(), true);
let x: OperationResult<i32, &str> = OperationResult::Err("Some other error message");
assert_eq!(x.is_retry(), false);
sourcepub fn is_err(&self) -> bool
pub fn is_err(&self) -> bool
Returns true
if the result is OperationResult::Err
.
Examples
Basic usage:
let x: OperationResult<i32, &str> = OperationResult::Ok(-3);
assert_eq!(x.is_err(), false);
let x: OperationResult<i32, &str> = OperationResult::Retry("Some error message");
assert_eq!(x.is_err(), false);
let x: OperationResult<i32, &str> = OperationResult::Err("Some other error message");
assert_eq!(x.is_err(), true);
