Struct ForEachRefHandler 

pub struct ForEachRefHandler<Row, F> { /* private fields */ }

A handler that calls a closure for each row using zero-copy RefFromRow.

Unlike ForEachHandler, this handler uses RefFromRow to decode rows as zero-copy references into the buffer. The closure receives a reference to the decoded struct.

Requirements

• The row type must implement RefFromRow
• All struct fields must use LengthPrefixed<T> with big-endian types
• All columns must be NOT NULL

Implementations

impl<Row, F> ForEachRefHandler<Row, F>

pub fn new(f: F) -> Self

Trait Implementations

impl<Row, F> ExtendedHandler for ForEachRefHandler<Row, F>

where Row: for<'a> RefFromRow<'a>, F: for<'a> FnMut(&'a Row) -> Result<()>,

fn row(&mut self, cols: RowDescription<'_>, row: DataRow<'_>) -> Result<()>

Called for each data row.

fn result_start(&mut self, cols: RowDescription<'_>) -> Result<()>

Called when a result set begins.

fn result_end(&mut self, complete: CommandComplete<'_>) -> Result<()>

Called when a result set ends.
