Struct ConstraintIndexNamer 

pub struct ConstraintIndexNamer<'a> { /* private fields */ }

Names the indexes of a relation’s keys one at a time, each after the keys named before it, as index_create names each new index.

Implementations

impl<'a> ConstraintIndexNamer<'a>

pub fn new( catalog: &'a dyn IndexNameCatalog, table: &str, ) -> Result<Self, SQLError>

pub fn occupy(&mut self, names: impl IntoIterator<Item = String>)

Constraints the statement creates on the relation before its keys, such as a new table’s CHECK and NOT NULL constraints.

pub fn name(&mut self, key: &mut TableKeyConstraint) -> Result<(), SQLError>

Name a key’s index. A retained key keeps its name; an explicit name must not belong to a relation, then to another constraint of the relation; any other key takes the first free generated name.
