Struct mz_adapter::catalog::CommentsMap

pub struct CommentsMap { /* private fields */ }

Implementations

impl CommentsMap

pub fn update_comment( &mut self, object_id: CommentObjectId, sub_component: Option<usize>, comment: Option<String> ) -> Option<String>

pub fn drop_comments( &mut self, object_id: CommentObjectId ) -> Vec<(CommentObjectId, Option<usize>, String)>

Remove all comments for object_id from the map.

Generally there is one comment for a given CommentObjectId, but in the case of relations you can also have comments on the individual columns. Dropping the comments for a relation will also drop all of the comments on any columns.

pub fn iter( &self ) -> impl Iterator<Item = (CommentObjectId, Option<usize>, &str)>

pub fn get_object_comments( &self, object_id: CommentObjectId ) -> Option<&BTreeMap<Option<usize>, String>>
