Trait FlattenCtxExt 

pub trait FlattenCtxExt<T>: Sized {
    // Required methods
    fn flatten_ctx(self, context: &'static str) -> Result<T>;
    fn flatten_ctx_with(self, context: String) -> Result<T>;
}

Substrate extension trait over anyhow::Result<T> — the ONE substrate owner of the .map_err(|e| anyhow::anyhow!("<ctx>: {e}")) display-prefix wrap-shape for consumers whose source error is already anyhow::Error. See the module docs for the full callsite audit + the naming rationale (why flatten_ctx and not anyhow::Context::context).

Required Methods

fn flatten_ctx(self, context: &'static str) -> Result<T>

Wrap the source anyhow::Error (if any) with a static context prefix, producing an anyhow::Result whose error Display reads exactly "<context>: <source display>".

fn flatten_ctx_with(self, context: String) -> Result<T>

Owned-string peer of Self::flatten_ctx — the escape hatch for consumers that compose the context slug via format! (e.g. format!("evaluate {:?}", c.kind) where the tail is only known at runtime).

Dyn Compatibility

This trait is not dyn compatible.

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