Noalloc
Noalloc is a Go toolkit and CLI to assert functions do not allocate on the heap and provide zero-allocating data structures.
Noalloc is a tool and library designed for Go developers to enforce zero heap allocations in codebases. It provides a CLI that checks entire call trees for heap allocations when functions are marked with directives. The tool identifies every line that allocates memory for remediation or exemption. It includes zero-allocating, fixed-sized data structures like Buf, Vec, Slice, and Map, along with a custom JSON encoder and decoder. Developers can use it to build high-performance web services and code search engines that require strict memory management. It requires Go 1.27 or later.
