本文简要介绍rust语言中 std::thread::Builder.stack_size 的用法。用法pub fn stack_size(self, size: usize) -> Builder 设置新线程的堆栈大小(以字节为单位)。 如果平台指定最小堆栈大小,则实际堆栈大小可能大于此值。 有关线程堆栈大小的更多信息,请参阅this module-level documentation。 例子 use std::...
I would like to declareValuestruct so that it can be created with variable sized arrays of bytes (where the size is known at compile time). I've tried: structValue{ t: TypeMarker, bytes: [u8;usize] } error[E0423]: expected value, found builtintype`usize` -->exa...

All data stored on the stack must have a known, fixed size. Data with an unknown size at compile time or a size that might change must be stored on the heap instead.所有栈区储存的数据必须是已知的、固定的内存大小。如果在编译时数据时未知的内存大小或者可能会变化的内存大小,那么该数据必须存储...
On Unix, this is running in signal context, which uses the alternative signal stack, which is usually a few KB in size (smallest size on supported Linux platforms seems to be 8K). It's possible to reconfigure this size using sigaltstack. EDIT: On Windows, Rust uses Vectored Exception Handl...

它们的 size 是编译时确定的,所以在栈中构造,编译时即可预留空间(通过减小 esp/rsp 寄存器的值),内存分配的效率比在堆中高,因为堆要在运行时执行分配算法。但前提是,由于 C/C++ 有指针这样的间接类型,要保证这些复合类型内的各成员,在构造时都没有使用堆。比如,一个内含 std::string 或者 char* p = new ...
