Struct BindStateMachine 

pub struct BindStateMachine { /* private fields */ }

State machine for binding a portal (Parse + Bind, no Execute/Sync).

Used by exec_iter to create a portal that can be executed multiple times.

Implementations

impl BindStateMachine

pub fn bind_prepared<P: ToParams>( buffer_set: &mut BufferSet, portal_name: &str, statement_name: &str, param_oids: &[Oid], params: &P, ) -> Result<Self>

Bind a prepared statement to a portal.

Writes Bind + Flush to buffer_set.write_buffer.

Uses the server-provided parameter OIDs to encode parameters.

Arguments

• portal_name: Portal name (empty string “” for unnamed portal)

pub fn bind_sql<P: ToParams>( buffer_set: &mut BufferSet, portal_name: &str, sql: &str, params: &P, ) -> Result<Self>

Parse raw SQL and bind to a portal.

Writes Parse + Bind + Flush to buffer_set.write_buffer.

Uses the natural OIDs from the parameters to inform the server about parameter types.

Arguments

• portal_name: Portal name (empty string “” for unnamed portal)

pub fn step(&mut self, buffer_set: &mut BufferSet) -> Result<Action>

Process input and return the next action.
