Enum retry::OperationResult [−][src]
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
Contains the success value.
Contains the error value if duration is exceeded.
Contains an error value to return immediately.
Implementations
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);
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);
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);
