Trait termwiz::error::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;
}

This trait allows extending the Result type so that it can create a termwiz::Error that wraps an underlying other error and provide additional context on that error.

Required Methods

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

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

Wrap the error value with additional context.

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

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

Wrap the error value with additional context that is evaluated lazily only once an error does occur.

Object Safety

This trait is not object safe.
