Struct odbc_api::RowSetCursor[−][src]

pub struct RowSetCursor<C: Cursor, B> { /* fields omitted */ }

A row set cursor iterates in blocks over row sets, filling them in buffers, instead of iterating the result set row by row. This is usually much faster.

Implementations

impl<C, B> RowSetCursor<C, B> where
    C: Cursor, [src]

pub fn fetch(&mut self) -> Result<Option<&B>, Error>[src]

Fills the bound buffer with the next row set.

Return

None if the result set is empty and all row sets have been extracted. Some with a reference to the internal buffer otherwise.
