There were Nagle's algorithm delays in both the "fresh_client" and
"reuse_client" versions of the .mp4 serving benchmark. Now performance is much
more consistent.
* don't store sizes of mp4-format sample indexes; recalculate them.
* keep SampleIndexIterator position as a u32 rather than a usize.
This is 960 bytes for a 60-minute mp4; another small cache usage improvement.
* add a --ts subcommand to convert between numeric and human-readable
representations. This is handy when directly inspecting the SQLite database
or API output.
* also take the human-readable form in the web interface's camera view.
* to reduce confusion, when using trim=true on the web interface's camera
view, trim the displayed starting and ending times as well as the actual
.mp4 file links.
This crate is a slightly-more-polished and MIT-licensed version of
resource.rs. So far it has one advantage: running the tests doesn't
require RUST_TEST_THREADS=1.
The benchmarks now require "cargo bench --features=nightly". The
extra #[cfg(nightly)] switches in the code needed for it are a bit
annoying; I may move the benches to a separate directory to avoid this.
But for now, this works.
This is a significant milestone; now the Rust branch matches the C++ branch's
features.
In the process, I switched from using serde_derive (which requires nightly
Rust) to serde_codegen (which does not). It was easier than I thought it'd
be. I'm getting close to no longer requiring nightly Rust.
