Struct odbc_api::buffers::OptFixedSizedColumn

pub struct OptFixedSizedColumn<T> { /* fields omitted */ }

Column buffer for fixed sized type, also binding an indicator buffer to handle NULL.

Implementations

impl<T> OptFixedSizedColumn<T> where
    T: Default + Clone, 

pub fn new(batch_size: usize) -> Self

pub unsafe fn value_at(&self, row_index: usize) -> Option<&T>

Access the value at a specific row index.

Safety

The buffer size is not automatically adjusted to the size of the last row set. It is the callers responsibility to ensure, a value has been written to the indexed position by Cursor::fetch using the value bound to the cursor with Cursor::set_num_result_rows_fetched.

pub fn values(&self) -> &[T]

pub fn indicators(&self) -> &[Len]

Trait Implementations

impl<T> ColumnBuffer for OptFixedSizedColumn<T> where
    T: FixedSizedCType, 

fn bind_arguments(&mut self) -> BindColParameters

Arguments used to describe the buffer then binding this column to a cursor.
