Currently `Debug` only prints the raw value:
ExitStatus(
unix_wait_status(
139,
),
)
That isn't very meaningful on its own since you may have to manually
decode the value to understand what happened. Change the implementation
to also include the `Display` representation, which provides more
user-friendly details.
ExitStatus(
unix_wait_status(139, "signal: 11 (SIGSEGV) (core dumped)"),
)
Update subtree sync docs
…round Remove /tmp workaround now that rustdoc fixed the disk usage issue
…ytes API to reduce RAM usage
Remove integer packing workaround and replace by the new_array_from_bytes API to reduce RAM usage
Use correct alignment for global variables
Make const strings readonly and remove the pointer indirection
…ures Fix to use target features from a target spec
and Extend for String too
