Function macro_tools::container_kind::of_type

pub fn of_type(ty: &Type) -> ContainerKind

Return kind of container specified by type.

Good to verify alloc::vec::Vec< i32 > is vector. Good to verify std::collections::HashMap< i32, i32 > is hash map.

Basic use-case.

use macro_tools::exposed::*;

let code = qt!( std::collections::HashMap< i32, i32 > );
let tree_type = syn::parse2::< syn::Type >( code ).unwrap();
let kind = container_kind::of_type( &tree_type );
assert_eq!( kind, container_kind::ContainerKind::HashMap );
