BlobDecls

Struct BlobDecls

pub struct BlobDecls { /* private fields */ }

Expand description

The blob declarations for a database handle, resolved from the declared set + the live schema at open. A synced table absent from this map carries no blob.

Implementations§

impl BlobDecls

pub fn ref_from_change( &self, change: &RowChange, ) -> Result<Option<BlobRef>, BlobDeclError>

The blob a single changeset row references, or None when the row’s table carries no blob or the blob id is absent/NULL. Reads the declared columns off the changeset row (which reports columns in schema order, the order the resolved indices address).
