Struct ExecutionOptions 

pub struct ExecutionOptions {
    pub max_intermediate_rows: Option<usize>,
    pub max_result_rows: Option<usize>,
    pub max_relationship_expansions: Option<u64>,
    pub timeout: Option<Duration>,
    pub cancellation_token: Option<CancellationToken>,
    pub observer: Option<ExecutionObserver>,
    pub procedures: Option<Procedures>,
    pub params: HashMap<String, PropertyValue>,
}

Per-statement safety limits and optional telemetry. Limit fields default to None, preserving unlimited behavior for trusted embedded callers.

Fields

max_intermediate_rows: Option<usize>

max_result_rows: Option<usize>

max_relationship_expansions: Option<u64>

timeout: Option<Duration>

cancellation_token: Option<CancellationToken>

observer: Option<ExecutionObserver>

procedures: Option<Procedures>

None (the default) means CALL always fails with “procedure not found” – MarsDB ships no built-in procedures itself, see procedure::ProcedureProvider’s own docs.

params: HashMap<String, PropertyValue>

The statement’s own $name parameters, verbatim – every other $param position is already resolved to a concrete Literal before Executor ever sees the statement (substitute_params, run during marsdb::prepare_statement, well before this point), but a standalone CALL proc written with no parens at all (TCK’s Call1 [2]/[11], Call2 [3]) resolves each declared input from a same-named $param – which declared names even exist isn’t knowable until the procedure’s signature is looked up here, at execution time (the registry itself, procedures above, isn’t available any earlier either), so this is the one place Executor still needs the raw map instead of already-substituted AST nodes.

Trait Implementations

fn clone(&self) -> ExecutionOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExecutionOptions

fn default() -> ExecutionOptions

Returns the “default value” for a type.
