Struct StrColumn

pub struct StrColumn(/* private fields */);

Implementations

impl StrColumn

pub fn wrap(bytes_column: BytesColumn) -> StrColumn

pub fn dictionary(&self) -> &Dictionary<VoidSSTable>

pub fn ord_to_str(&self, term_ord: u64, output: &mut String) -> Result<bool>

Fills the buffer

Methods from Deref<Target = BytesColumn>

pub fn ord_to_bytes(&self, ord: u64, output: &mut Vec<u8>) -> Result<bool>

Fills the given output buffer with the term associated to the ordinal ord.

Returns false if the term does not exist (e.g. term_ord is greater or equal to the overll number of terms).

pub fn num_rows(&self) -> RowId

Returns the number of rows in the column.

pub fn term_ords(&self, row_id: RowId) -> impl Iterator<Item = u64> + '_

pub fn ords(&self) -> &Column<u64>

Returns the column of ordinals

pub fn num_terms(&self) -> usize

pub fn dictionary(&self) -> &Dictionary<VoidSSTable>
