Trait ResultExt 

pub trait ResultExt<T>: Sealed {
    // Required methods
    fn context<C: Config, D>(
        self,
        id: C::Id,
        message: impl Into<Cow<'static, str>>,
    ) -> Result<T, C, D>;
    fn context_auto<C: Config, D>(
        self,
        message: impl Into<Cow<'static, str>>,
    ) -> Result<T, C, D>;
    fn wrap_err<C: Config, D>(self, gerr: GErr<C, D>) -> Result<T, C, D>;
}

Extension for Result wrapping E as any error.

This is for general error, including GErr itself.

Passing GErr will be parsed as general error.

Required Methods

fn context<C: Config, D>( self, id: C::Id, message: impl Into<Cow<'static, str>>, ) -> Result<T, C, D>

Wrap E inside GErr as source with manually-set id.

fn context_auto<C: Config, D>( self, message: impl Into<Cow<'static, str>>, ) -> Result<T, C, D>

Wrap E inside GErr as source with auto-generated id and code.

fn wrap_err<C: Config, D>(self, gerr: GErr<C, D>) -> Result<T, C, D>

Wrap E inside GErr

Dyn Compatibility

This trait is not dyn compatible.

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