You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: interface.rs
    path of file: ./repos/shame/shame_graph/src/expr
    
    the code of the file until where you have to start completion: 
use std::ops::{Deref, Range};

use crate::{any::Any, common::{IteratorExt, ranges_overlap}, context::Context, error::Error};

use super::*;

pub type Loc = u32; //Location, Set index or Binding index

pub struct InterfaceBlock(pub(crate) Vec<Any>);

impl Deref for InterfaceBlock {
    type Target = [Any];
    fn deref(&self) -> &[Any] {&self.0}
}

impl InterfaceBlock {
    pub fn new(members: Ve
    
    pub fn push_vertex_attribute_with_location_iter<T: Iterator<Item=u32>>(&mut self, loc_iter: &mut LocationIter<T>, tensor: Tensor, ident: Option<String>) -> (Any, Range<u32>) {
        let loc_range = loc_iter.next(tensor.shape.col_count() as u32)
        .expect("vertex attribute iterator exhausted"); //TODO: think about making this function return a Result, and all the repercussions of that
        let any = Any::global_interface(tensor.into_ty().as_const(), ident);
        self.vertex_attributes.push((loc_range.clone(), any));
        (any, loc_range)
    }
