Struct odbc_api::buffers::TextRowSet

pub struct TextRowSet { /* fields omitted */ }

This row set binds a string buffer to each column, which is large enough to hold the maximum length string representation for each element in the row set at once.

Implementations

impl TextRowSet

pub fn new(
    batch_size: UInteger,
    cursor: &Cursor<'_>
) -> Result<TextRowSet, Error>

Use cursor to query the display size for each column of the row set and allocates the buffers accordingly.

pub fn at(&self, col_index: usize, row_index: usize) -> Option<&[u8]>

Access the element at the specified position in the row set.

pub fn at_as_str(
    &self,
    col_index: usize,
    row_index: usize
) -> Result<Option<&str>, Utf8Error>

Access the element at the specified position in the row set.

pub fn num_cols(&self) -> usize

Return the number of columns in the row set.

pub fn num_rows(&self) -> usize

Return the number of rows in the row set.
