```
size_t BufferSizeForStructuredProtoField (StructuredProtoField field)
```
Estimates the number of bytes needed to encode `field` using

protobuf encoding.

The returned value might be larger than the actual number of bytes needed.

```
const absl::Status * _Nonnull AsStatus (const absl::Status & s)
```
Convert a Status or a StatusOr to its underlying status value.

(This implementation does not require a dep on absl::Status to work.)

```
bool EncodeVarint (uint64_t tag, uint64_t value, absl::Span<char> * buf)
```
Encodes the specified integer as a varint field and returns true if it fits.

Used for int32_t, int64_t, uint32_t, uint64_t, bool, and enum field types.

Consumes up to kMaxVarintSize * 2 bytes (20).
```
bool Encode64Bit (uint64_t tag, uint64_t value, absl::Span<char> * buf)
```
Encodes the specified integer as a 64-bit field and returns true if it fits.

Used for fixed64 and sfixed64 field types.

Consumes up to kMaxVarintSize + 8 bytes (18).
```
bool Encode32Bit (uint64_t tag, uint32_t value, absl::Span<char> * buf)
```
Encodes the specified integer as a 32-bit field and returns true if it fits.

Used for fixed32 and sfixed32 field types.

Consumes up to kMaxVarintSize + 4 bytes (14).
```
absl::Span<char> EncodeMessageStart (uint64_t tag, uint64_t max_size, absl::Span<char> * buf)
```
Encodes the header for a length-delimited field containing up to `max_size`

bytes or the number remaining in the buffer, whichever is less. If the

header fits, a non-nullptr `Span` is returned; this must be passed to

`EncodeMessageLength` after all contents are encoded to finalize the length

field. If the header does not fit, a nullptr `Span` is returned which is

safe to pass to `EncodeMessageLength` but need not be.

Used for string, bytes, message, and packed-repeated field type.

Consumes up to kMaxVarintSize * 2 bytes (20).
```
void EncodeMessageLength (absl::Span<char> msg, const absl::Span<char> * buf)
```
Finalizes the length field in `msg` so that it encompasses all data encoded

since the call to `EncodeMessageStart` which returned `msg`. Does nothing if

`msg` is a `nullptr` `Span`.

size_t BufferSizeFor (uint64_t tag, WireType type)
```
`BufferSizeFor` returns a number of bytes guaranteed to be sufficient to

store encoded fields as `(tag, WireType)`, regardless of data values. This

only makes sense for `WireType::kLengthDelimited` if you add in the length of

the contents yourself, e.g. for string and bytes fields by adding the lengths

of any encoded strings to the return value or for submessage fields by

enumerating the fields you may encode into their contents.

bool EncodeStructuredProtoField (StructuredProtoField field, absl::Span<char> & buf)

Encodes `field` into `buf` using protobuf encoding.

On success, returns `true` and advances `buf` to the end of

the bytes consumed.

On failure (if `buf` was too small), returns `false`.
```

bool IsCharStarOrVoidStar ()
```
If the comparison will happen as pointers, decay `char*` arguments to `void*`

when printing them. There is no evidence that they are a NULL terminated

C-String so printing them as such could lead to UB, and more importantly we

compared pointers so showing the pointers is a better result.

const T & GetReferenceableValue (const T & t)
```
`CHECK_EQ` and friends want to pass their arguments by reference, however

this winds up exposing lots of cases where people have defined and

initialized static const data members but never declared them (i.e. in a .cc

file), meaning they are not referenceable. This function avoids that problem

for integers (the most common cases) by overloading for every primitive

integer type, even the ones we discourage, and returning them by value.
