Trait ResultExt 

pub trait ResultExt: Sized + Sealed {

    // Required methods
    fn is_err_or(self, f: impl FnOnce(Self::T) -> bool) -> bool;
    fn is_ok_or(self, f: impl FnOnce(Self::E) -> bool) -> bool;

Required Methods

fn is_err_or(self, f: impl FnOnce(Self::T) -> bool) -> bool

fn is_ok_or(self, f: impl FnOnce(Self::E) -> bool) -> bool

fn contains<U>(&self, u: &U) -> bool

where Self::T: PartialEq<U>,

fn contains_err<U>(&self, u: &U) -> bool

where Self::E: PartialEq<U>,

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.
