Function spacetimedb_bindings_sys::delete_by_rel

source · 
pub fn delete_by_rel(table_id: TableId, relation: &[u8]) -> Result<u32, Errno>
Expand description

Deletes those rows, in the table identified by table_id, that match any row in relation.

Matching is defined by first BSATN-decoding the byte string pointed to at by relation to a Vec<ProductValue> according to the row schema of the table and then using Ord for AlgebraicValue.

Returns the number of rows deleted.

Returns an error if

  • a table with the provided table_id doesn’t exist
  • (relation, relation_len) doesn’t decode from BSATN to a Vec<ProductValue>
