unit-tests: Fix `cargo test` on 32-bit platforms
Fixes https://bz.mercurial-scm.org/show_bug.cgi?id=6506
This makes `IndexEntryBuilder::build`, which is only used in unit tests, use
`u32` or `u64` instead of platform-dependent `usize` when packing binary data
to be used at test input.
To run Rust unit tests in 32-bit mode in a x86-64 environment, use:
rustup target add i686-unknown-linux-gnu # Once
(cd rust && cargo test --target i686-unknown-linux-gnu)

'''measure performance of Mercurial commands
Using ``hgperf`` instead of ``hg`` measures performance of the target
Mercurial command. For example, the execution below measures
performance of :hg:`heads --topo`::
$ hgperf heads --topo
All command output via ``ui`` is suppressed, and just measurement
result is displayed: see also "perf" extension in "contrib".
Costs of processing before dispatching to the command function like
below are not measured::
- parsing command line (e.g. option validity check)
- reading configuration files in
But ``pre-`` and ``post-`` hook invocation for the target command is
measured, even though these are invoked before or after dispatching to
the command function, because these may be required to repeat
execution of the target command correctly.
