Type Definition witcher::Result

type Result<T, E = Error> = Result<T, E>;

Result<T> is a simplified return type to use throughout your application.

Trait Implementations

impl<T, E> Wrapper<T, E> for Result<T, E> where
    E: StdError + Send + Sync + 'static, 

pub fn pass(self) -> Result<T>

Pass the error through without any message. This is useful to keep compatibility without having to unwrap the error.

pub fn wrap(self, msg: &str) -> Result<T>

Wrap the error providing the ability to add more context

pub fn err_is<U>(&self) -> bool where
    U: StdError + 'static, 

Check if there is an error and the err is the given error type

pub fn retry<F>(self, max: usize, f: F) -> Result<T, E> where
    F: Fn(usize) -> Result<T, E>, 

Retry the given function when we have an error max number of times.

pub fn retry_on<F>(self, max: usize, id: TypeId, f: F) -> Result<T, E> where
    F: Fn(usize) -> Result<T, E>, 

Retry the given function when we have the concreate error U max number of times.
