rust: make `Revision` a newtype...
rust: make `Revision` a newtype This change is the one we've been building towards during this series. The aim is to make `Revision` mean more than a simple integer, holding the information that it is valid for a given revlog index. While this still allows for programmer error, since creating a revision directly and querying a different index with a "checked" revision are still possible, the friction created by the newtype will hopefully make us think twice about which type to use. Enough of the Rust ecosystem relies on the newtype pattern to be efficiently optimized away (even compiler in codegen tests¹), so I'm not worried about this being a fundamental problem.

Mercurial

Mercurial is a fast, easy to use, distributed revision control tool for software developers.

Basic install:

$ make            # see install targets
$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.

Notes for packagers

Mercurial ships a copy of the python-zstandard sources. This is used to provide support for zstd compression and decompression functionality. The module is not intended to be replaced by the plain python-zstandard nor is it intended to use a system zstd library. Patches can result in hard to diagnose errors and are explicitly discouraged as unsupported configuration.
