Wrap Self in a Result based off a predicate.

Provided methods

fn ok_if<E>(self, predicate: bool, err: E) -> Result<Self, E>[src]

Results Ok(self) if the predicate returns true, or Err(err) otherwise.

fn with_ok_if<F, E>(self, predicate: F, err: E) -> Result<Self, E> where
    F: FnOnce(&Self) -> bool, [src]

Results Ok(self) if the predicate returns true, or Err(err) otherwise.

fn err_if<E>(self, predicate: bool, err: E) -> Result<Self, E>[src]

Results Err(err) if the predicate returns true, or Ok(self) otherwise.

fn with_err_if<F, E>(self, predicate: F, err: E) -> Result<Self, E> where
    F: FnOnce(&Self) -> bool, [src]

Results Err(err) if the predicate returns true, or Ok(self) otherwise.
