Trait IntoResult 

pub trait IntoResult
where
    Self: Sized,
{
    // Provided methods
    fn ok_if<E>(self, predicate: bool, err: E) -> Result<Self, E> { ... }
    fn with_ok_if<F, E>(self, predicate: F, err: E) -> Result<Self, E>
       where F: FnOnce(&Self) -> bool { ... }
    fn err_if<E>(self, predicate: bool, err: E) -> Result<Self, E> { ... }
    fn with_err_if<F, E>(self, predicate: F, err: E) -> Result<Self, E>
       where F: FnOnce(&Self) -> bool { ... }
}

Wrap Self in a Result based off a predicate.

Provided Methods

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

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,

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

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

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,

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
