Struct WriteBatch 

pub struct WriteBatch<R: GridRow> { /* private fields */ }

Operations collected by GridWriter::batch, written when its closure returns and published in one snapshot. Each method writes what the GridWriter method of the same name writes.

Implementations

impl<R: GridRow> WriteBatch<R>

pub fn upsert(&mut self, row: impl Into<Arc<R>>)

Inserts or replaces a row by key and highlights the changed columns.

pub fn upsert_silent(&mut self, row: impl Into<Arc<R>>)

Inserts or replaces a row by key without highlight.

pub fn mark_changed(&mut self, key: R::Key, columns: ColumnSet)

Highlights columns of an existing row without replacing it.

pub fn remove(&mut self, key: R::Key)

Removes a row by key.

pub fn replace_all(&mut self, rows: impl IntoIterator<Item = Arc<R>>)

Replaces every row, without highlight.

pub fn clear(&mut self)

Removes every row.

pub fn set_pinned_rows( &mut self, edge: PinnedEdge, rows: impl IntoIterator<Item = Arc<R>>, )

Replaces the rows pinned at edge; see GridWriter::set_pinned_rows.

pub fn set_progress(&mut self, progress: Option<GridProgress>)

Shows (Some) or clears (None) the store’s progress; never buffered by a running reload.

pub fn finish_reload( &mut self, reload: Reload<R>, snapshot: impl IntoIterator<Item = Arc<R>>, )

Finishes reload with the rows it returned, at this point of the batch: writes before it in the batch are buffered by the reload, and writes after it are published with the reloaded rows. Ignored if a newer reload superseded it, like Reload::finish. A reload of another store is finished there at once, outside the batch.
