[PATCH v3 02/15] xdiff: introduce rust

From
Ezekiel Newren via GitGitGadget <gitgitgadget@gmail.com>
Date
Aug 23, 2025, 03:55 UTC
Message-ID
<03939951256baaaec3fcc690cfa38ee12fb553ce.1755921357.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.1980.v3.git.git.1755921356.gitgitgadget@gmail.com>
From: Ezekiel Newren <ezekielnewren@gmail.com>

Upcoming patches will simplify xdiff, while also porting parts of it to Rust. In preparation, add some stubs and setup the Rust build. For now, it is easier to let cargo build rust and have make or meson merely link against the static library that cargo builds. In line with ongoing libification efforts, use multiple crates to allow more modularity on the Rust side. xdiff is the crate that this series will focus on, but we also introduce the interop crate for future patch series.

In order to facilitate interoperability between C and Rust, introduce C definitions for Rust primitive types in git-compat-util.h.
