Description
Issue Description
Problem:
When compiling the sqlite crate (version 0.37.0) on ARM Linux after vendoring dependencies, we encounter a syntax error in the vendored source code:
error: expected identifier, found keyword use
--> /home/uos/rust/batch/vendor/sqlite-0.37.0/src/cursor.rs:193:72
|
193 | pub fn iter(&self) -> impl Iterator<Item = (&'_ str, &'_ Value)> + use<'_> {
| ^^^ expected identifier, found keyword
Cause:
The code incorrectly uses use (a Rust keyword) as a trait name in the return type declaration. This is invalid Rust syntax. The issue occurs only on ARM Linux, while the same code compiles successfully on x86 Linux, suggesting a potential difference in compiler versions or target-specific behavior.
Solution Implemented
To resolve this issue while maintaining vendored dependencies, I implemented the following solution:
Modified the problematic source file:
Path to the problematic file
FILE_PATH="/home/uos/rust/batch/vendor/sqlite-0.37.0/src/cursor.rs"
Fix the syntax error by replacing invalid syntax
sed -i '193s/+ use<'''>/ + '''/' $FILE_PATH
Updated checksum verification:
Path to checksum file
CHECKSUM_FILE="/home/uos/rust/batch/vendor/sqlite-0.37.0/.cargo-checksum.json"
Calculate new SHA256 checksum
NEW_CHECKSUM=$(sha256sum $FILE_PATH | awk '{print $1}')
Update checksum in JSON file
jq --arg file "src/cursor.rs"
--arg checksum "$NEW_CHECKSUM"
'.files[$file] = $checksum' $CHECKSUM_FILE > temp.json
mv temp.json $CHECKSUM_FILE
Verification Steps
After implementing the solution:
The syntax error is resolved by changing + use<'> to the valid + ' lifetime bound
The checksum file is updated to match the modified file
The project compiles successfully on ARM Linux
