CowRewriteFile

iceberg::cow_rewrite

Struct CowRewriteFile 

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

A data file selected for COW rewrite.

This is a read-only output type: the planning entry points that produce candidates are crate-internal and reached through crate::cow_rewrite::CowRewriteBuilder, and the fields are exposed through accessors only. Follow-up commit-adapter work (overwrite and row-delta actions) consumes planned candidates through those accessors; construction from outside the crate is intentionally not exposed yet and can be added when an adapter actually needs it.
