Trait oneline_template::function_executor::FunctionExecutor

pub trait FunctionExecutor {
    fn schema(&self) -> FunctionSchema;
    fn call(
        &self, 
        input: Value, 
        arguments: &[Value]
    ) -> Result<Value, FunctionError>;
}

Executes function.

Required methods

fn schema(&self) -> FunctionSchema

Returns function schema that contain information about function: function name and argument types.

fn call(
    &self,
    input: Value,
    arguments: &[Value]
) -> Result<Value, FunctionError>

Executes function.

• input value that retrieved from field or other function executor.
• arguments list of arguments that was declared within template.
