Trait dbkit_engine::block::RefColumn

pub trait RefColumn<'re> {
    fn attribute(&self) -> &Attribute;
    fn capacity(&self) -> usize;
    fn rows_raw_slice(&'re self) -> &'re [u8];
    fn nulls_raw_slice(&'re self) -> &'re [u8];
    unsafe fn rows_ptr(&self) -> *const u8;
    unsafe fn nulls_ptr(&self) -> *const u8;
}

Trait representing a reference to column data. Data can be owned by current object or references from another one.

Required Methods

fn attribute(&self) -> &Attribute

fn capacity(&self) -> usize

fn rows_raw_slice(&'re self) -> &'re [u8]

Will panic if there's no row data

fn nulls_raw_slice(&'re self) -> &'re [u8]

Will panic if there's no null data

unsafe fn rows_ptr(&self) -> *const u8

Pointer to the beginning of the raw row data. ptr can be nil

unsafe fn nulls_ptr(&self) -> *const u8

Pointer to the beginning of the raw row data. ptr can be nil
