Struct WireFnSignature 

Source 
pub struct WireFnSignature {
    pub args: Vec<WireArgType>,
    pub returns: WireArgType,
    pub volatility: String,
    pub null_handling: String,
}
Expand description

Wire-level scalar / aggregate / procedure signature shipped by a plugin’s register export.

String-based for wire stability — plugins shouldn’t have to encode arrow_schema::DataType JSON. Translation to internal FnSignature / AggSignature / ProcedureSignature happens at adapter construction time (M6a.1.5 / M6a.2).

Fields§

§args: Vec<WireArgType>

Argument types in WireArgType form.

§returns: WireArgType

Return type.

§volatility: String

Volatility — "immutable", "stable", or "volatile". Default "immutable".

§null_handling: String

Null handling — "propagate" (default) or "user_handled".
