Trait err_ctx::ResultExt

pub trait ResultExt<T, E> where
    E: Into<Box<dyn Error + Send + Sync>>, {
    fn ctx<D>(self, context: D) -> Result<T, Context<D>>;
    fn with_ctx<D>(
        self, 
        f: impl FnOnce(&E) -> D
    ) -> Result<T, Context<D>>;
}

Required methods

fn ctx<D>(self, context: D) -> Result<T, Context<D>>

If this Result is an Err, wrap the error with context.

fn with_ctx<D>(
    self,
    f: impl FnOnce(&E) -> D
) -> Result<T, Context<D>>

If this Result is an Err, invoke f and wrap the error with its result.
