Use inline to vastly simplify the exposed API. This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
Now they use slices or array pointers with any element type instead of
requiring byte pointers.
This is a breaking enhancement to the language.
The safety check for overlapping pointers will be implemented in a
future commit.
closes#14040
It seems like the original code of setsockopt is not effective because
i catch the EINVAL branch when uncomment this code, it should call
setsockopt before the bind call.
This should fix issue #14900.

This fixes a bug in std.net caused during the introduction of
meta.assumeSentinel due to the unfortunate semantics of mem.span()
This leaves only 3 remaining uses of meta.assumeSentinel() in the
standard library, each of which could be a simple @ptrCast([*:0]T, foo)
instead. I think this function should likely be removed.
Here's what I landed on for the TLS client. It's 16896 bytes
(max_ciphertext_record_len is 16640). I believe this is the theoretical
minimum size, give or take a few bytes.
These constraints are satisfied:
* a call to the readvAdvanced() function makes at most one call to the
underlying readv function
* iovecs are provided by the API, and used by the implementation for
underlying readv() calls to the socket
* the theoretical minimum number of memcpy() calls are issued in all
circumstances
* decryption is only performed once for any given TLS record
* large read buffers are fully exploited
This is accomplished by using the partial read buffer to storing both
cleartext and ciphertext.
The read function has been renamed to readAdvanced since it has slightly
different semantics than typical read functions, specifically regarding
the end-of-file. A higher level read function is implemented on top.
Now, API users may pass small buffers to the read function and
everything will work fine. This is done by re-decrypting the same
ciphertext record with each call to read() until the record is finished
being transmitted.
If the buffer supplied to read() is large enough, then any given
ciphertext record will only be decrypted once, since it decrypts
directly to the read() buffer and therefore does not need any memcpy. On
the other hand, if the buffer supplied to read() is small, then the
ciphertext is decrypted into a stack buffer, a subset is copied to the
read() buffer, and then the entire ciphertext record is saved for the
next call to read().
* Export invalidFmtErr
To allow consistent use of "invalid format string" compile error
response for badly formatted format strings.
See https://github.com/ziglang/zig/pull/13489#issuecomment-1311759340.
* Replace format compile errors with invalidFmtErr
- Provides more consistent compile errors.
- Gives user info about the type of the badly formated value.
* Rename invalidFmtErr as invalidFmtError
For consistency. Zig seems to use “Error” more often than “Err”.
* std: add invalid format string checks to remaining custom formatters
* pass reference-trace to comp when building build file; fix checkobjectstep
