Struct EngineAction 

pub struct EngineAction<'a, R>
where
    R: EvaluationContext,
{ /* private fields */ }

Minimal edit surface used by Engine::action.

This wrapper is intentionally thin for ticket 614 (commit-only): it delegates to existing Engine edit methods and does not create changelog boundaries or implement rollback.

Implementations

impl<'a, R> EngineAction<'a, R>

where R: EvaluationContext,

pub fn name(&self) -> &str

pub fn set_cell_value( &mut self, sheet: &str, row: u32, col: u32, value: LiteralValue, ) -> Result<(), EditorError>

pub fn set_cell_formula( &mut self, sheet: &str, row: u32, col: u32, ast: ASTNode, ) -> Result<(), EditorError>

pub fn insert_rows( &mut self, sheet: &str, before: u32, count: u32, ) -> Result<ShiftSummary, EditorError>

pub fn delete_rows( &mut self, sheet: &str, start: u32, count: u32, ) -> Result<ShiftSummary, EditorError>

pub fn insert_columns( &mut self, sheet: &str, before: u32, count: u32, ) -> Result<ShiftSummary, EditorError>

pub fn delete_columns( &mut self, sheet: &str, start: u32, count: u32, ) -> Result<ShiftSummary, EditorError>

pub fn action<T>( &mut self, name: impl AsRef<str>, f: impl FnOnce(&mut EngineAction<'_, R>) -> Result<T, EditorError>, ) -> Result<T, EditorError>

Start an action from within an action.

Nested actions are currently disallowed (ticket 614), so this will return a EditorError::TransactionFailed while an outer action is active.
