Struct BufferRegistryTextProvider 

Source 
pub struct BufferRegistryTextProvider { /* private fields */ }
Expand description

D.3.a (2026-05-29): the production BufferTextProvider impl. Bridges the trait to the host’s crate::buffer_registry::BufferRegistry: buffer_rope(id) walks BufferRegistry::document_handle(id) -> RopeDocumentHandle::snapshot() -> snapshot.buffer.to_rope().

All operations are RCU-style reads (registry mutex held only long enough to clone an Arc<DocumentSnapshot>; rope clone is Arc-share of chunks). Safe to call from spawn_blocking. Returns None for non-document buffers or for ids the registry has dropped — the diff subsystem’s BufferSource impl maps None to an empty rope per its documented contract.
