Example
---
```rust
fn foo() {
let foo = Some("foo");
return foo.and$0(Some("bar"));
}
```
**Before this PR**
```rust
fn foo() {
let foo = Some("foo");
return foo.and_then(|| Some("bar"));
}
```
**After this PR**
```rust
fn foo() {
let foo = Some("foo");
return foo.and_then(|it| Some("bar"));
}
```
---
```rust
struct Func { f: fn() -> i32 }
fn foo() {
let foo = true;
let func = Func { f: || 2 };
let x = foo.then$0(func.f);
}
```
**Before this PR**
```text
request handler panicked: Failed to make ast node `syntax::ast::generated::nodes::CallExpr` from text const C: () = func.f();
```
**After this PR**
```rust
struct Func { f: fn() -> i32 }
fn foo() {
let foo = true;
let func = Func { f: || 2 };
let x = foo.then_some((func.f)());
}

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
