Trait Context 

pub trait Context<T> {
    // Required methods
    fn context(self, context: impl Into<String>) -> Result<T, CaptureError>;
    fn with_context<S: Into<String>>(
        self,
        f: impl FnOnce() -> S,
    ) -> Result<T, CaptureError>;
}

Attach context to a fallible value, mapping its error into CaptureError::Backend while preserving the original cause. Mirrors anyhow::Context, so a call site only has to import crate::error::Context instead of anyhow::Context.

Required Methods

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

Wrap the error with a fixed context message.

fn with_context<S: Into<String>>( self, f: impl FnOnce() -> S, ) -> Result<T, CaptureError>

Wrap the error with a lazily-built context message (only computed on error).

Dyn Compatibility

This trait is not dyn compatible.

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