//! or code inside an `assert_no_alloc!` macro interacts with the allocator in any way.
|
||||
//! Wanton allocations and unforeseen drops no more - this library lets you focus on
|
||||
//! writing code without worrying if Rust properly managed to inline the variable into the stack.
|
||||
//!
|
||||
//!
|
||||
//! Now, an allocator blowing up in production is a scary thought; that's why QADAPT
|
||||
//! is designed to strip its own code out whenever you're running with a release build.
|
||||
//! Just like the [`debug_assert!` macro](https://doc.rust-lang.org/std/macro.debug_assert.html)
|
||||
//! in Rust's standard library, it's safe to use without worrying about a unforeseen
|
||||
//! circumstance causing your application to crash.
|
||||
//!
|
||||
//!
|
||||
//! # Usage
|
||||
//!
|
||||
//!
|
||||
//! Actually making use of QADAPT is straight-forward. To set up the allocator,
|
||||
//! place the following snippet in either your program binaries (main.rs) or tests:
|
||||
//!
|
||||
//!
|
||||
//! ```rust,ignore
|
||||
//! use qadapt::QADAPT;
|
||||
//!
|
||||
//!
|
||||
//! #[global_allocator]
|
||||
//! static Q: QADAPT = QADAPT;
|
||||
//! ```
|
||||
//!
|
||||
//!
|
||||
//! After that, there are two ways of telling QADAPT that it should trigger a panic:
|
||||
//!
|
||||
//!
|
||||
//! 1. Annotate functions with the `#[no_alloc]` proc macro:
|
||||
//! ```rust,no_run
|
||||
//! use qadapt::no_alloc;
|
||||
//!
|
||||
//!
|
||||
//! #[no_alloc]
|
||||
//! fn do_math() -> u8 {
|
||||
//! 2 + 2
|
||||
//! }
|
||||
//! ```
|
||||
//!
|
||||
//!
|
||||
//! 2. Evaluate expressions with the `assert_no_alloc!` macro
|
||||
//! ```rust,no_run
|
||||
//! use qadapt::assert_no_alloc;
|
||||
//!
|
||||
//!
|
||||
//! fn do_work() {
|
||||
//! // This code is allowed to trigger an allocation
|
||||
//! let b = Box::new(8);
