Struct ColumnGrants 

pub struct ColumnGrants {
    pub grantee: GranteeType,
    pub relation: DbObjectId,
    pub with_grant_option: bool,
    pub privilege_columns: BTreeMap<String, BTreeSet<String>>,
    pub depends_on: Vec<DbObjectId>,
    pub rep_id: String,
}

Column-level grants for a single (grantee, relation, grant-option) tuple, grouped by privilege so they render as one statement.

Grant identity stays per-column everywhere else in the model (catalog fetch, Grant::id(), dependency tracking); this is purely an output-shaping representation built right before ordering.

Fields

grantee: GranteeType

relation: DbObjectId

The owning relation (Table or View). Column grants reference the bare relation in SQL, with the columns attached to each privilege.

with_grant_option: bool

privilege_columns: BTreeMap<String, BTreeSet<String>>

Privilege -> the columns it applies to, e.g. {"SELECT": {"a", "b"}, "UPDATE": {"a"}}. Sorted map/sets keep the rendered privilege and column order stable across runs.

depends_on: Vec<DbObjectId>

What this grant orders after — always the owning relation.

rep_id: String

The id of one constituent per-column grant, used as this operation’s identity for dependency ordering. For GrantColumns it names a grant present in the new catalog; for RevokeColumns, one present in the old catalog — so ordering resolves the relation edge in the correct direction (create: relation -> grant; drop: revoke -> relation).

Implementations

impl ColumnGrants

pub fn relation_schema_and_name(&self) -> (String, String)

The (schema, name) of the owning relation. The relation is always a table or view (the only relations with grantable columns).

Trait Implementations

impl Clone for ColumnGrants

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnGrants

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
