Trait tree_sitter_graph::functions::Parameters

pub trait Parameters {
    // Required methods
    fn param(&mut self) -> Result<Value, ExecutionError>;
    fn finish(&mut self) -> Result<(), ExecutionError>;
}

A helper trait for consuming the parameters of a function. You will typically use it as follows:

let first_param = params.param()?.into_string()?;
let second_param = params.param()?.as_integer()?;
// etc
params.finish()?;

Required Methods

fn param(&mut self) -> Result<Value, ExecutionError>

Returns the next parameter, returning an error if you have exhausted all of the parameters that were passed in.

fn finish(&mut self) -> Result<(), ExecutionError>

Ensures that there are no more parameters to consume.
