Struct ColumnIpv6 

pub struct ColumnIpv6 { /* private fields */ }

Column for IPv6 addresses (stored as FixedString(16) - 16 bytes)

Implementation Note: Unlike C++, this does NOT delegate to ColumnFixedString because IPv6 data is pure binary (not UTF-8 text). Rust’s ColumnFixedString uses String which requires valid UTF-8 and trims null bytes, corrupting binary IPv6 data. Direct Vec<[u8; 16]> storage is more appropriate and preserves bulk copy performance.

Implementations

impl ColumnIpv6

pub fn new(type_: Type) -> Self

Create a new empty IPv6 column.

pub fn with_data(self, data: Vec<[u8; 16]>) -> Self

Set the column data from a vector of 16-byte arrays.

pub fn append_from_string(&mut self, s: &str) -> Result<()>

Append an IPv6 address parsed from a string.

Supports both full and compressed formats (e.g., "::1", "fe80::1").

Errors

Returns an error if the string is not a valid IPv6 address.

pub fn append(&mut self, bytes: [u8; 16])

Append IPv6 from 16-byte array

pub fn at(&self, index: usize) -> [u8; 16]

Get IPv6 at index as 16-byte array

pub fn as_string(&self, index: usize) -> String

Format IPv6 at index as string

pub fn len(&self) -> usize

Returns the number of values in this column.

pub fn is_empty(&self) -> bool

Returns true if the column contains no values.

Trait Implementations

impl Column for ColumnIpv6

fn column_type(&self) -> &Type

Get the type of this column

fn size(&self) -> usize

Get the number of rows in this column

fn clear(&mut self)

Clear all data from the column

fn reserve(&mut self, new_cap: usize)

Reserve capacity for at least new_cap elements

fn append_column(&mut self, other: ColumnRef) -> Result<()>

Append another column’s data to this column

fn load_from_buffer(&mut self, buffer: &mut &[u8], rows: usize) -> Result<()>

Load column data from byte buffer

fn save_to_buffer(&self, buffer: &mut BytesMut) -> Result<()>

Save column data to byte buffer

fn clone_empty(&self) -> ColumnRef

Create an empty clone of this column (same type, no data)

fn slice(&self, begin: usize, len: usize) -> Result<ColumnRef>

Create a slice of this column

fn as_any(&self) -> &dyn Any

Downcast to a concrete column type

fn as_any_mut(&mut self) -> &mut dyn Any

Downcast to a mutable concrete column type

fn load_prefix(&mut self, _buffer: &mut &[u8], _rows: usize) -> Result<()>

Load column prefix from byte buffer (for types that need prefix data) Default implementation is a no-op. Override for types like LowCardinality. This matches C++ clickhouse-cpp’s LoadPrefix pattern.

fn save_prefix(&self, _buffer: &mut BytesMut) -> Result<()>

Save column prefix to byte buffer (for types that need prefix data) Default implementation is a no-op. Override for types like LowCardinality, Array with special nested types. This matches C++ clickhouse-cpp’s SavePrefix pattern.
