Summary

Type parameters are placed inside angle brackets

Type parameters can be used on structs, functions, impl blocks, and more

Type parameters allow you to create placeholders that will be filled in with concrete types, instead of duplicating your definitions

Type parameters can be a comma separated list, and are supposed to be UpperCamelCased

When you use type parameters to define a struct, you put the angle brackets immediately after the struct’s name

When you use type parameters to define a function, you put the angle brackets immediately after the function’s name

When you use type parameters in an impl block, you declare the type parameters immediately after the impl keyword, and then use the type parameters in angle brackets with the struct’s name

When you need to disambiguate a type, you can use the ::<Turbofish>
