Enum BindingsDef 

pub enum BindingsDef {
    Map(HashMap<String, String>),
    PolydatSource(String),
}

How bindings are defined for an op.

Two modes:

• Map: Legacy nosqlbench-style name: "FuncA(); FuncB()" chains. Each binding is independent; inheritance merges at key level.
• PolydatSource: Native Polydat grammar as a multiline string. The entire binding block is a single Polydat program with coordinates, named outputs, and full DAG wiring. Replaces (not merges with) any inherited bindings.

Variants

Map(HashMap<String, String>)

Legacy nosqlbench-style: name → expression chain.

PolydatSource(String)

Native Polydat grammar source text.

Implementations

impl BindingsDef

pub fn is_empty(&self) -> bool

Returns true if there are no bindings defined.

pub fn as_map(&self) -> &HashMap<String, String>

Get the map view (for legacy code). Returns empty map for PolydatSource.

pub fn insert(&mut self, key: String, value: String)

Insert a key-value pair (legacy map mode). Converts PolydatSource to Map.

Trait Implementations

impl Clone for BindingsDef

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingsDef

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

Formats the value using the given formatter.

impl Default for BindingsDef

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BindingsDef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for BindingsDef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
