rust: Read dirstate from disk in DirstateMap constructor Before this changeset, Python code first creates an empty `DirstateMap` Rust object, then immediately calls its `read` method with a byte string of the contents of the `.hg/dirstate` file. This makes that byte string available to the constructor of `DirstateMap` in the hg-cpython crate. This is a first step towards enabling parts of `DirstateMap` in the hg-core crate to borrow from this buffer without copying. Differential Revision: https://phab.mercurial-scm.org/D10556

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.
