Enum Column 

pub enum Column {
    Float64(Vec<f64>),
    Int64(Vec<i64>),
    String(Vec<Option<Arc<str>>>),
    Bool(Vec<Option<bool>>),
}

Type-specific column storage for SIMD operations.

Each variant stores values in a contiguous Vec for cache-friendly SIMD processing. Missing values are represented as:

• f64::NAN for Float64
• i64::MIN for Int64
• None for String and Bool

Variants

Float64(Vec<f64>)

Float64 column with NaN for missing values

Int64(Vec<i64>)

Int64 column with i64::MIN for missing values

String(Vec<Option<Arc<str>>>)

String column with Option for nullable strings

Bool(Vec<Option<bool>>)

Bool column with Option for nullable bools

Implementations

impl Column

pub const fn len(&self) -> usize

Returns the number of elements in the column.

pub const fn is_empty(&self) -> bool

Returns true if the column is empty.

pub fn as_float64(&self) -> Option<&[f64]>

Returns the Float64 slice if this is a Float64 column.

pub fn as_int64(&self) -> Option<&[i64]>

Returns the Int64 slice if this is an Int64 column.

pub fn as_string(&self) -> Option<&[Option<Arc<str>>]>

Returns the String slice if this is a String column.

pub fn as_bool(&self) -> Option<&[Option<bool>]>

Returns the Bool slice if this is a Bool column.

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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