Enum ibc_relayer::util::retry::RetryResult

source · [−]

pub enum RetryResult<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

impl<T, E> OperationResult<T, E>

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);

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);

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);
