Trait Context 

pub trait Context<T, E> {
    // Required methods
    fn context<C>(self, context: C) -> Result<T>
       where C: Display + Send + Sync + 'static;
    fn with_context<C, F>(self, f: F) -> Result<T>
       where C: Display + Send + Sync + 'static,
             F: FnOnce() -> C;
}

anyhow::Context-like trait for adding contexts and getting Errors.

Required Methods

fn context<C>(self, context: C) -> Result<T>

where C: Display + Send + Sync + 'static,

See anyhow::Context::context.

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

where C: Display + Send + Sync + 'static, F: FnOnce() -> C,

See anyhow::Context::with_context.

Dyn Compatibility

This trait is not dyn compatible.

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