Member Function Documentation

get_access_token()

string_view mastodonpp::Instance::get_access_token ( ) const

inline

Returns the access token.

Since

0.1.0

    {
        return _access_token;
    }

get_baseuri()

string_view mastodonpp::Instance::get_baseuri ( ) const

inline

Returns the base URI.

The base URI is “https://” + the hostname.

    {
        return _baseuri;
    }

get_hostname()

string_view mastodonpp::Instance::get_hostname ( ) const

inline

Returns the hostname.

Since

0.1.0

    {
        return _hostname;
    }

get_max_chars()

uint64_t mastodonpp::Instance::get_max_chars

(

)

Returns the maximum number of characters per post.
