Trait ResultExt

pub trait ResultExt<T, E>
where
    E: Into<Box<dyn Error + Send + Sync>>,
{
    // Required methods
    fn ctx<D>(self, context: D) -> Result<T, Context<D>>;
    fn with_ctx<D>(self, f: impl FnOnce(&E) -> D) -> Result<T, Context<D>>;
}

Required Methods

fn ctx<D>(self, context: D) -> Result<T, Context<D>>

If this Result is an Err, wrap the error with context.

fn with_ctx<D>(self, f: impl FnOnce(&E) -> D) -> Result<T, Context<D>>

If this Result is an Err, invoke f and wrap the error with its result.

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.
