Trait ResultExt

pub trait ResultExt<T> {
    // Required methods
    fn context<C>(self, context: C) -> Result<T, Error>
       where C: AsRef<str>;
    fn with_context<F>(self, context: F) -> Result<T, Error>
       where F: FnOnce() -> String;
    fn e(self) -> Result<T, Error>;
}

Required Methods

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

where C: AsRef<str>,

fn with_context<F>(self, context: F) -> Result<T, Error>

where F: FnOnce() -> String,

fn e(self) -> Result<T, Error>

Quickly convert a std error into a Error, without having to write a context message.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
