Tynm -- Type Name

Returns type names with a specifiable number of module segments as a String.

```rust // === std library === // asserteq!( std::any::typename::>(), "core::option::Option", );

// === tynm === // // Simple type name: asserteq!(tynm::typename::>(), "Option",);

// Type name with 1 module segment, starting from the most significant module. asserteq!( tynm::typenamem::>(1), "core::..::Option", );

// Type name with 1 module segment, starting from the least significant module. asserteq!( tynm::typenamen::>(1), "..::option::Option<..::string::String>", );

// Type name with 1 module segment from both the most and least significant modules.

[rustfmt::skip]

mod rustout { pub mod two { pub mod three { pub struct Struct; } } } asserteq!( tynm::typenamemn::(1, 1), "rustout::..::three::Struct", ); ```

Motivation

The [std::any::type_name] function stabilized in Rust 1.38 returns the fully qualified type name with all module segments. This can be difficult to read in error messages, especially for type-parameterized types.

Often, the simple type name is more readable, and enough to distinguish the type referenced in an error.
