Struct LiveGrid 

pub struct LiveGrid { /* private fields */ }

Shows views of a densa_data::LiveTable in the grid, formatted like an ArrowTable.

It keeps a formatter for each of the live table’s batches; view brings them up to date first, which allocates only when batches were added or compacted since the last call. Columns are sized from the first rows, as in ArrowTable. Given another table (or a clone), it rebuilds its formatters; for a table with another schema it also resets its column settings.

Implementations

impl LiveGrid

pub fn new(table: &LiveTable) -> Self

A grid for views of table, with formatters for its current batches.

pub fn columns(&self) -> Vec<Column>

Grid columns, as ArrowTable::columns.

pub fn set_decimals( &mut self, column: usize, decimals: Option<usize>, ) -> Result<(), TableError>

As ArrowTable::set_decimals.

Errors

TableError::NoSuchColumn if there is no such column.

pub fn set_column_chars( &mut self, column: usize, chars: usize, ) -> Result<(), TableError>

As ArrowTable::set_column_chars.

Errors

TableError::NoSuchColumn if there is no such column.

pub fn view<'a>( &'a mut self, table: &'a LiveTable, view: ViewId, first_row: usize, palette: &Palette, ) -> Option<LiveGridView<'a>>

A GridSource showing view view of table from first_row (scrolled), or None if the view does not exist. Call it each frame, after the table’s changes.
