Struct ColumnHandle 

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

Handle for accessing a named extra column. O(1) via Vec index.

Implementations

impl ColumnHandle

pub fn index(self) -> usize

The raw index used for Vec-based O(1) lookups.

Trait Implementations

impl Clone for ColumnHandle

fn clone(&self) -> ColumnHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ColumnHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ColumnHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ColumnHandle

fn eq(&self, other: &ColumnHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
