Required Methods

fn want<S: Into<String>>(self, desc: S) -> Self

👎Deprecated since 0.7.0:

use doing(…) for action contexts; use at(…) for locator/resource contexts

fn position<S: Into<String>>(self, desc: S) -> Self

Provided Methods

fn attach_context<C: Into<OperationContext>>(self, ctx: C) -> Self

where Self: Sized,

👎Deprecated since 0.7.0:

use with_context(…) for full context frames; use doing(…) / at(…) for semantic context helpers

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.
