具体而言,文件中的 NormalizeArrayLen 结构体实现了 MirPass<'tcx> trait,表示这是一个用于 MIR 转换的处理器。它分析 MIR 中的数组,并尝试将其长度标准化为常量。 而Replacer<'tcx> 结构体在这个过程中起到了替换作用。它是 rustc_hir::intravisit::Visitor trait 的一个实现,遍历 MIR,并为每个数组长度所...

When we load wasm, we can pass in the object: WebAssembly.instantiateStreaming(fetch("utils.gc.wasm"),importObject) 1. It return a promise, we can run the exported function return by wasm inside the promise. Now we are going to create a function in Rust: ...

在Rust源代码中,rust/compiler/rustc_lint/src/array_into_iter.rs文件的作用是实现与数组迭代器相关的功能。该文件定义了ArrayIntoIter结构体及其相关实现。 首先介绍一下ArrayIntoIter结构体,它是一个用于数组迭代的迭代器。ArrayIntoIter结构体的定义如下: pub struct ArrayIntoIter<T, const N: usize> { inner...
