Struct MapMapping 

pub struct MapMapping {
    pub path: String,
    pub logic: Value,
    pub logic_index: Option<usize>,
}

A single mapping that transforms and assigns data.

The mapping evaluates a JSONLogic expression against the message context and assigns the result to the specified path.

Fields

path: String

Target path where the result will be stored (e.g., “data.user.name”). Supports dot notation for nested paths and # prefix for numeric field names.

logic: Value

JSONLogic expression to evaluate. Can reference any field in the context using {"var": "path.to.field"} syntax.

logic_index: Option<usize>

Index into the compiled logic cache. Set during workflow compilation.
