Classes | |
class | Array |
An Array is a JSON array, which contains heterogeneous JSON values. More... | |
class | Object |
An Object is a JSON object, which maps strings to heterogenous JSON values. More... | |
class | ObjectKey |
ObjectKey is a used to capture keys in Object. More... | |
class | ObjectMapper |
Helper for mapping JSON objects onto protocol structs. More... | |
class | OStream |
json::OStream allows writing well-formed JSON without materializing all structures as json::Value ahead of time. More... | |
class | ParseError |
class | Path |
A "cursor" marking a position within a Value. More... | |
class | Value |
A Value is an JSON value of unknown type. More... | |
Functions | |
bool | isUTF8 (llvm::StringRef S, size_t *ErrOffset=nullptr) |
Returns true if S is valid UTF-8, which is required for use as JSON. | |
std::string | fixUTF8 (llvm::StringRef S) |
Replaces invalid UTF-8 sequences in S with the replacement character (U+FFFD). | |

llvm::Expected< Value > | parse (llvm::StringRef JSON) |
Parses the provided JSON source, or returns a ParseError. | |
template<typename T > | |
Expected< T > | parse (const llvm::StringRef &JSON, const char *RootName="") |
Version of parse() that converts the parsed value to the type T. | |
llvm::raw_ostream & | operator<< (llvm::raw_ostream &OS, const Value &V) |
Serializes this Value to JSON, writing it to the provided stream. | |
static void | quote (llvm::raw_ostream &OS, llvm::StringRef S) |
Variables | |
template<typename T > | |
constexpr bool | is_uint_64_bit_v |
std::string llvm::json::fixUTF8 | ( | llvm::StringRef | S | ) |
Replaces invalid UTF-8 sequences in S
with the replacement character (U+FFFD).
The returned string is valid UTF-8. This is much slower than isUTF8, so test that first.

bool llvm::json::isUTF8 | ( | llvm::StringRef | S, |

Returns true if S
is valid UTF-8, which is required for use as JSON.
If it returns false, Offset
is set to a byte offset near the first error.

inline |
Serializes this Value to JSON, writing it to the provided stream.
The formatting is compact (no extra whitespace) and deterministic. For pretty-printing, use the formatv() format_provider below.

Expected< T > llvm::json::parse | ( | const llvm::StringRef & | JSON, |
const char * | RootName = "" |
||
) |
Version of parse() that converts the parsed value to the type T.
RootName describes the root object and is used in error messages.
