All parts of the protozero header-only library are in this namespace.
using protozero::pbf_length_type = typedef uint32_t |
The type used for length values, such as the length of a field.
using protozero::pbf_tag_type = typedef uint32_t |
The type used for field tags (field numbers).
using protozero::pbf_writer = typedef basic_pbf_writer<std::string> |
Specialization of basic_pbf_writer using std::string as buffer type.
|
strong |
The type used to encode type information. See the table on https://developers.google.com/protocol-buffers/docs/encoding
|
inlinenoexcept |
Varint encode a 64 bit integer.
data | Where to add the varint. There must be enough space available! |
value | The integer that will be encoded. |
|
inline |
Varint encode a 64 bit integer.
TBuffer | A buffer type. |
buffer | Output buffer the varint will be written to. |
value | The integer that will be encoded. |
Any | exception thrown by calling the buffer_push_back() function. |
|
inline |
Decode a 64 bit varint.
Strong exception guarantee: if there is an exception the data pointer will not be changed.
[in,out] | data | Pointer to pointer to the input data. After the function returns this will point to the next data to be read. |
[in] | end | Pointer one past the end of the input data. |
varint_too_long_exception | if the varint is longer then the maximum length that would fit in a 64 bit int. Usually this means your data is corrupted or you are trying to read something as a varint that isn't. |
end_of_buffer_exception | if the end of the buffer was reached before the end of the varint. |
|
inlineconstexprnoexcept |
Decodes a 32 bit ZigZag-encoded integer.
|
inlineconstexprnoexcept |
Decodes a 64 bit ZigZag-encoded integer.
|
inlineconstexprnoexcept |
ZigZag encodes a 32 bit integer.
|
inlineconstexprnoexcept |
ZigZag encodes a 64 bit integer.
|
inlinenoexcept |
Get the length of the varint the specified value would produce.
value | The integer to be encoded. |
|
inlineconstexprnoexcept |
Two data_view instances are not equal if they have different sizes or the content differs.
lhs | First object. |
rhs | Second object. |
Returns true if lhs.compare(rhs) < 0.
lhs | First object. |
rhs | Second object. |
Returns true if lhs.compare(rhs) <= 0.
lhs | First object. |
rhs | Second object. |
|
inlineconstexprnoexcept |
Two data_view instances are equal if they have the same size and the same content.
lhs | First object. |
rhs | Second object. |
Returns true if lhs.compare(rhs) > 0.
lhs | First object. |
rhs | Second object. |
Returns true if lhs.compare(rhs) >= 0.
lhs | First object. |
rhs | Second object. |
|
inline |
Skip over a varint.
Strong exception guarantee: if there is an exception the data pointer will not be changed.
[in,out] | data | Pointer to pointer to the input data. After the function returns this will point to the next data to be read. |
[in] | end | Pointer one past the end of the input data. |
end_of_buffer_exception | if the end of the buffer was reached before the end of the varint. |
|
inlinenoexcept |
Swap two basic_pbf_writer objects.
lhs | First object. |
rhs | Second object. |
Swap two data_view objects.

rhs | Second object. |
|
inlineconstexprnoexcept |
Get the tag and wire type of the current field in one integer suitable for comparison with a switch statement.
See pbf_reader.tag_and_type() for an example how to use this.
|
inline |
Varint encode a 64 bit integer.

value | The integer that will be encoded. |
Any | exception thrown by increment or dereference operator on data. |
|
constexpr |
