Trait BindingTuple 

pub trait BindingTuple: Sized {
    // Required method
    fn from_binding_vec(
        expected: usize,
        vec: Option<Vec<Binding>>,
    ) -> Result<Option<Self>, ProjectorError>;
}

A BindingTuple is any type that can accommodate a Mentat tuple query result of fixed length.

Currently Rust tuples of length 1 through 6 (i.e., (A) through (A, B, C, D, E, F)) are supported as are vectors (i.e., Vec<>).

Required Methods

fn from_binding_vec( expected: usize, vec: Option<Vec<Binding>>, ) -> Result<Option<Self>, ProjectorError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
