Trait ErrorContext 

pub trait ErrorContext<T> {
    // Required methods
    fn error<M: Into<Cow<'static, str>>>(self, message: M) -> Result<T>;
    fn or_error<M: Into<Cow<'static, str>>, F: FnOnce() -> M>(
        self,
        f: F,
    ) -> Result<T>;
}

Required Methods

fn error<M: Into<Cow<'static, str>>>(self, message: M) -> Result<T>

fn or_error<M: Into<Cow<'static, str>>, F: FnOnce() -> M>( self, f: F, ) -> Result<T>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
