Trait ValueObjectExt 

pub trait ValueObjectExt {
    // Required method
    fn as_object_mut_or(
        &mut self,
        slot: &'static str,
    ) -> Result<&mut Map<String, Value>>;
}

Substrate extension trait over serde_json::Value — the ONE substrate owner of the .as_object_mut().ok_or_else(|| anyhow!( "<slot> is not an object")) guard-shape. See the module docs for the full callsite audit + the naming rationale (why as_object_mut_or and not as_object_mut).

Required Methods

fn as_object_mut_or( &mut self, slot: &'static str, ) -> Result<&mut Map<String, Value>>

Borrow the Value as a mutable JSON object Map, or fail loud with an anyhow::Error whose Display reads exactly "<slot> is not an object" — the pre-lift wire format every consumer’s tracing::error!(error = %e, ...) log line already encoded.

Dyn Compatibility

This trait is dyn compatible.

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