Struct BinColumnView

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

Implementations§

Source§

impl<'c> BinColumnView<'c>

Source

pub fn len(&self) -> usize

The number of valid elements in the text column.

Source

pub fn is_empty(&self) -> bool

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

Source

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

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

Source

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

Iterator over the valid elements of the text buffer

Source

pub fn has_truncated_values(&self) -> Option<Indicator>

Finds an indicator larger than max element 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.
