Struct PreparedReadLease 

pub struct PreparedReadLease { /* private fields */ }

A prepared stream lease. Dropping a partially consumed HTTP response uses the same registry cancellation path as POST .../cancel.

Implementations

impl PreparedReadLease

pub fn columns(&self) -> Vec<ColumnInfo>

pub fn preview_stream(&self) -> Option<PreparedResultStream>

Open a second immutable cursor for response-size preflight. It never exposes rows to a caller and leaves the delivery cursor untouched.

pub fn next_row(&mut self) -> Option<Vec<SqlValue>>

Returns a row only while the registered execution remains successful. A cancellation that arrives between HTTP body polls is observed before the next row is made available to the response stream.

pub fn summary(&self) -> ReadExecutionSummary

pub fn finish(self)

Discard coordinator-owned result state after the terminal summary was delivered successfully. A small terminal tombstone remains only until registry cleanup, keeping repeated cancellation idempotent.

Trait Implementations

impl Drop for PreparedReadLease

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
