Trait ResultExt 

pub trait ResultExt<T> {
    // Required methods
    fn context<S: Into<String>>(self, context: S) -> Result<T>;
    fn with_context<F, S>(self, f: F) -> Result<T>
       where F: FnOnce() -> S,
             S: Into<String>;
}

Extension trait for adding context to Results in async operations

Required Methods

fn context<S: Into<String>>(self, context: S) -> Result<T>

Add context to an error

fn with_context<F, S>(self, f: F) -> Result<T>

where F: FnOnce() -> S, S: Into<String>,

Add context to an error using a closure (lazy evaluation)

This trait is not dyn compatible.

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