Struct dbkit_engine::block::Block

pub struct Block<'b> {
    // some fields omitted
}

A container for column data conforming to a pre-defined schema. This container is the owner of the columns (and their data)

Methods

impl<'b> Block<'b>

fn new(alloc: &'b Allocator, schema: &Schema) -> Block<'b>

fn capacity(&self) -> RowOffset

fn set_capacity(&mut self, row_cap: RowOffset) -> Option<DBError>

Grow possible row space for each column

fn add_row(&mut self) -> Result<RowOffset, DBError>

Returns rowid of the added row

fn column_mut(&mut self, pos: usize) -> Option<&mut Column<'b>>

Mutable reference to column and its data.
