Trait libbpf_rs::ErrorExt

pub trait ErrorExt: Sealed {
    type Output;

    // Required methods
    fn context<C>(self, context: C) -> Self::Output
       where C: IntoCowStr;
    fn with_context<C, F>(self, f: F) -> Self::Output
       where C: IntoCowStr,
             F: FnOnce() -> C;
}

A trait providing ergonomic chaining capabilities to Error.

Required Associated Types

type Output

The output type produced by context and with_context.

Required Methods

fn context<C>(self, context: C) -> Self::Output

where C: IntoCowStr,

Add context to this error.

fn with_context<C, F>(self, f: F) -> Self::Output

where C: IntoCowStr, F: FnOnce() -> C,

Add context to this error, using a closure for lazy evaluation.

Object Safety

This trait is not object safe.
