Whenever the body of a function contradicts the function’s signature, the signature takes precedence; the signature is right and the body is wrong.

Good example for this golden rule in Rust is that it does not have function signatures.

Rust has module feature. It can be used to hierarchically split code in logical units. You can manage visibility like public, and private.

A module is a collection of items: functions, structs, traits, impl blocks, and even other modules.

There are actually different ways in Rust to create iterators from types. While the IntoIterator and its into_iter() method are mostly called implicitly when we use forloops, iter() and iter_mut() methods are often provided by collection types to create iterators explicitly. There’s no trait that provides iter() and iter_mut(), so it’s more of a convention that collection types may implement these methods. 

The example from above can then be written as follows:

let employees = vec!["John", "Elvis", "David", "Calvin"];

let mut iterator_emp = (employees).iter(); 

println!("{}", iterator_emp.next().unwrap());
println!("{}", iterator_emp.next().unwrap());
println!("{}", iterator_emp.next().unwrap());
println!("{}", iterator_emp.next().unwrap());

Java and other languages have error management. Rust has following unique features in Rust:

• Recoverable/ “true” errors – Result enum is the key one which helps in recoverable error management. Errors can bubble up
• Non-recoverable / “exceptions” – Panics and UnWraps support non recoverable error management. Stopping the whole program or gracefully exit the application is the only option

Introduced May 6, Rust 1.52 was led by an enhancement to tooling support for Clippy, which is a collection of lints to find mistakes and improve Rust code. Previously, running cargo check followed by cargo clippy would not actually run Clippy, with the build caching in Cargo not differentiating between the two. This has been fixed in Rust 1.52. Also in version 1.52, the following methods were stabilized:

• Arguments::as_str
• char::MAX
• char::REPLACEMENT_CHARACTER
• char::UNICODE_VERSION
• char::decode_utf16
• char::from_digit
• char::from_u32_unchecked
• char::from_u32
• slice::partition_point
• str::rsplit_once
• str::split_once

Several previously stable APIs, including char::len_utf8 and u8LLeq_ignore_ascii_case, are now const. For the compiler, the default LLVM has been upgraded to LLVM 12. A subsequent point release of the language, Rust 1.52.1, published May 10, provides a workaround for a bug in incremental compilation that was made into a compiler error in Rust 1.52.0. Rust builders recommend either an upgrade to 1.52.1 or disabling incremental compilation.Accenture transforms legal group with analytics, natural language processinghttps://imasdk.googleapis.com/js/core/bridge3.470.1_en.html#goog_1860296949Volume 0% 

The changes planned for Rust 2021 are listed below :

• Additions to the prelude
• Default Cargo feature resolver
• IntoIterator for arrays
• Disjoint capture in closures
• Panic macro consistency
• Reserving syntax
• Promoting two warnings to hard errors
• Or patterns in macro_rules

Rust 1.56 will be available by september with these changes
