Trait pingora_core::Context

pub trait Context<T> {
    // Required method
    fn err_context<C, F>(self, context: F) -> Result<T, Box<Error>>
       where C: Into<ImmutStr>,
             F: FnOnce() -> C;
}

Helper trait to add more context to a given error

Required Methods

fn err_context<C, F>(self, context: F) -> Result<T, Box<Error>>

where C: Into<ImmutStr>, F: FnOnce() -> C,

Wrap the Err(E) in Result with more context, the existing E will be the cause.

This is a shortcut for map_err() + more_context()

Object Safety

This trait is not object safe.
