Functions

delete

delete removes the rows described by the KeySet from the table. It succeeds whether or not the keys were present.

insert_map

insert_or_update

insert_or_update returns a Mutation to insert a row into a table. If the row already exists, it updates it instead. Any column values not explicitly written are preserved.

insert_or_update_map

insert_or_update returns a Mutation to insert a row into a table. If the row already exists, it updates it instead. Any column values not explicitly written are preserved.

insert_or_update_struct

insert_or_update_struct returns a Mutation to insert a row into a table, specified by a Go struct. If the row already exists, it updates it instead. Any column values not explicitly written are preserved. For a similar example, See update_struct.

insert_struct

insert_struct returns a Mutation to insert a row into a table, specified by a Rust struct. If the row already exists, the write or transaction fails with codes.AlreadyExists.

replace

replace_map

replace_map returns a Mutation to insert a row into a table, deleting any existing row. Unlike InsertOrUpdateMap, this means any values not explicitly written become NULL. The row is specified by a map of column to value.

update

update returns a Mutation to update a row in a table. If the row does not already exist, the write or transaction fails.
