parameter

using corespace::parameter = std::pair<std::string, std::string>

Single query parameter: key=value (pre-encoding is handled by libcurl).

Definition at line 60 of file utils.hpp.

parameter_list

using corespace::parameter_list = std::vector<parameter>

Ordered list of query parameters appended to the URL.

Enumeration Type Documentation

entity_kind

enum class corespace::entity_kind

strong

Wikidata entity kind.

Names include the canonical identifier prefixes for clarity:

• item (IDs such as "Q123"), property ("P45"), lexeme ("L7"), mediainfo ("M9"), entity_schema ("E2"), form ("L7-F1"), sense ("L7-S2"). any acts as an API selector; unknown denotes an invalid or unrecognized identifier.

Enumerator
item	IDs prefixed with 'Q'.
property	IDs prefixed with 'P'.
lexeme	IDs prefixed with 'L'.
mediainfo	IDs prefixed with 'M'.
entity_schema	IDs prefixed with 'E'.
form	Lexeme form IDs such as "L<lexeme>-F<form>".
sense	Lexeme sense IDs such as "L<lexeme>-S<sense>".
any	API selector (e.g., flush(any)); not directly batchable.
unknown	Unrecognized/invalid identifier.

Function Documentation

random_hex()

std::string corespace::random_hex

(

const std::size_t

n

)

Return exactly n random hexadecimal characters (lowercase).

The function draws 4-bit nibbles from the shared PRNG. Characters are not zero-padded beyond the requested length; each position is an independent, uniformly distributed hex digit.

Definition at line 33 of file rng.cpp.

                                        {
    static constexpr char digits[] = "0123456789abcdef";
    static thread_local std::uniform_int_distribution<int> nibble(0, 15);
 
    std::string out;
    out.resize(n);
    auto& g = rng();
    for (std::size_t i = 0; i < n; ++i) {
        out[i] = digits[nibble(g)];
    }
    return out;
}

rng()

std::mt19937_64 & corespace::rng

(

)

Shared PRNG seeded on first use.

The generator is a process-wide std::mt19937_64 seeded from std::random_device. Calls from multiple threads share the same engine and therefore require external synchronization if deterministic ordering is important.

Definition at line 28 of file rng.cpp.

                     {
    static std::mt19937_64 gen { std::random_device {}() };
    return gen;
}
