Field Documentation

byte

const std::size_t nlohmann::detail::parse_error::byte

byte index of the parse error

The byte index of the last read character in the input file.

Note

For an input with n bytes, 1 is the index of the first character and n+1 is the index of the terminating null byte or the end of file. This also holds true when reading a byte vector (CBOR or MessagePack).

Definition at line 2938 of file json.hpp.

id

const int nlohmann::detail::exception::id

inherited

the id of the exception

Definition at line 2818 of file json.hpp.

m

std::runtime_error nlohmann::detail::exception::m

privateinherited

an exception object as storage for error messages
