Trait StdContextExt 

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

Adds .context(..) / .with_context(..) to a Result carrying any foreign std::error::Error, converting it to an Error::Internal along the way.

Required Methods

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

Converts the foreign error to Error and attaches context.

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

Converts the foreign error to Error and attaches a lazily-built context message.

Dyn Compatibility

This trait is not dyn compatible.

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