Function assert_input

pub fn assert_input(
    parameters: &[Parameter],
    arguments: &Map<FullValue>,
    function: &str,
    package: &str,
    kind: PackageKind,
) -> Result<(), LetError>

Edited: now returning LetErrors.

Tries to confirm that what we’re told to put in the function is the same as the function accepts.

Arguments

• parameters: The list of what the function accepts as parameters as returned by container.yml.
• arguments: The arguments we got to pass to the function.
• function: The name of the function we’re trying to evaluate (used for debugging purposes).
• package: The name of the internal package (used for debugging purposes).
• kind: The kind of the internal package (used for debugging purposes).

Returns
Nothing if the assert went alright, but a LetError describing why it failed on an error.
