@waynexia please check this
I suppressed the warning but clippy requires .truncate to be called before file creation
--> datafusion/substrait/src/serializer.rs:32:39
|
32 | let mut file = OpenOptions::new().create(true).write(true).open(path)?;
| ^^^^^^^^^^^^- help: add: `.truncate(true)`
|
= help: if you intend to overwrite an existing file entirely, call `.truncate(true)`
= help: if you instead know that you may want to keep some parts of the old file, call `.truncate(false)`
= help: alternatively, use `.append(true)` to append to the file instead of overwriting it
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#suspicious_open_options
= note: `-D clippy::suspicious-open-options` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(clippy::suspicious_open_options)]`

This is an interesting change -- basically it means that all ScalarValue based code will potentially consume significantly more memory (as now each ScalarValue takes 64 bytes rather than 48). Interestingly, this is the same behavior as aarch64 in previous rust versions (you can see this test is cfg'd off with
#[cfg(not(target_arch = "aarch64"))]I'll make a follow on PR to remove this cfg
