Module report 

Type-erased report data structures.

This module implements type erasure for error reports through vtable-based dispatch. The design allows reports with any context type C to be stored uniformly while maintaining the ability to format and inspect them.

Structure

• data: Contains ReportData<C>, the #[repr(C)] wrapper that pairs a context value with its vtable, children, and attachments
• raw: Contains RawReport, RawReportRef, and RawReportMut - the type-erased pointer types that users of this module interact with
• vtable: Contains ReportVtable, the function pointer table for type-erased operations

Allocation Strategy

Reports use Arc<ReportData<C>> for storage, enabling cheap cloning and shared ownership. The Arc is converted to a raw pointer for type erasure, then reconstructed when dropping or accessing with the concrete type.

Re-exports

pub use raw::RawReport;

pub use raw::RawReportMut;

pub use raw::RawReportRef;
