Module db 

The SQL backend abstraction: values, rows, batches, and the Db trait.

Structs

DbColumnDescription

One column of an introspected table (see DbTableDescriptor).

DbRow

One result row: a positional list of column values.

DbStatementResult

The outcome of a single statement once its batch has committed.

DbTableDescriptor

An existing table’s shape as reported by backend introspection (Db::describe_table). Used by schema reconciliation to compare the live table against the declared schema.

StmtId

Identifies one statement queued into a DbBatch.

ValueBinder

Builds a parameterized statement: each bind_next records a value and returns its placeholder string, so a query builder can splice placeholders into SQL text and hand the collected values to the driver in bind order.

Enums

DbError

An error from a SQL backend operation.

DbType

A generic SQL storage class, independent of any data protocol.

DbValue

A Db value — used for both parameters and query results.

Traits

Db

A SQL backend: reads, one-off writes/DDL, and a factory for atomic batches.

DbBatch

An atomic, all-or-nothing unit of writes.
