Struct SelectionVector 

pub struct SelectionVector { /* private fields */ }

An owned duckdb_selection_vector of size u32 indices.

Implementations

impl SelectionVector

pub fn new(size: u64) -> Option<SelectionVector>

Creates a selection vector holding size indices (initially unspecified; fill them with set).

Errors

Returns None if DuckDB fails to allocate.

pub fn len(&self) -> u64

The number of indices this selection vector holds.

pub fn is_empty(&self) -> bool

Whether the selection vector holds no indices.

pub fn set(&mut self, at: u64, row: u32)

Sets the index at position at to row.

Panics

Panics if at >= len().

pub fn get(&self, at: u64) -> Option<u32>

The index at position at, or None if at >= len().

Trait Implementations

impl Drop for SelectionVector

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
