Struct odbc_api::buffers::BinColumnView

pub struct BinColumnView<'c> { /* private fields */ }

Implementations

impl<'c> BinColumnView<'c>

pub fn len(&self) -> usize

The number of valid elements in the text column.

pub fn is_empty(&self) -> bool

True if, and only if there are no valid rows in the column buffer.

pub fn get(&self, index: usize) -> Option<&'c [u8]>

Slice of text at the specified row index without terminating zero.

pub fn iter(&self) -> BinColumnIt<'c>

Iterator over the valid elements of the text buffer

pub fn has_truncated_values(&self) -> bool

true if any value is truncated in the range [0, num_rows).

After fetching data we may want to know if any value has been truncated due to the buffer not being able to hold elements of that size. This method checks the indicator buffer element wise.
