I found these versions empirically, by using the following process:
First, I used `cargo tree --depth 1 --kind all` to get a list of
every immediate dependency we had.
Then, I used `cargo upgrade --workspace package@version` to change
each dependency to the earliest version with which (in theory) the
current version is semver-compatible. IOW, if the current version
was 3.2.3, I picked "3". If the current version was 0.12.8, I
picked "0.12".
Then, I used `cargo +nightly upgrade -Z minimal-versions` to
downgrade Cargo.lock to the minimal listed version for each
dependency. (I had to override a few packages; see .gitlab-ci.yml
for details).
Finally, I repeatedly increased the version of each of our
dependencies until our code compiled and the tests passed. Here's
what I found that we need:
anyhow >= 1.0.5: Earlier versions break our hyper example.
async-broadcast >= 0.3.2: Earlier versions fail our tests.
async-compression 0.3.5: Earlier versions handled futures and tokio
differently.
async-trait >= 0.1.2: Earlier versions are too buggy to compile our
code.
clap 2.33.0: For Arg::default_value_os().
coarsetime >= 0.1.20: exposed as_ticks() function.
curve25519-dalek >= 3.2: For is_identity().
generic-array 0.14.3: Earlier versions don't implement
From<&[T; 32]>
httparse >= 1.2: Earlier versions didn't implement Error.
itertools at 0.10.1: For at_most_once.
rusqlite >= 0.26.3: for backward compatibility with older rustc.
serde 1.0.103: Older versions break our code.
serde_json >= 1.0.50: Since we need its Value type to implement Eq.
shellexpand >= 2.1: To avoid a broken dirs crate version.
tokio >= 1.4: For Handle::block_on().
tracing >= 0.1.18: Previously, tracing_core and tracing had separate
LevelFilter types.
typenum >= 1.12: Compatibility with rust-crypto crates
x25519-dalek >= 1.2.0: For was_contributory().
Closes #275.

retry-error
An error attempt to represent multiple failures.
This crate implements [RetryError], a type to use when you
retry something a few times, and all those attempts. Instead of
returning only a single error, it records all of the errors
received, in case they are different.
This crate is developed as part of Arti, a project to implement Tor in Rust. It's used by higher-level crates that retry operations.
Example
use retry_error::RetryError;
fn some_operation() -> anyhow::Result<bool> {
unimplemented!(); // example
}
fn example() -> Result<(), RetryError<anyhow::Error>> {
const N_ATTEMPTS: usize = 10;
let mut err = RetryError::in_attempt_to("perform an example operation");
for _ in 0..N_ATTEMPTS {
match some_operation() {
Ok(val) => return Ok(()),
Err(e) => err.push(e),
}
}
// All attempts failed; return all the errors.
return Err(err);
}
