Struct yrs::YOutput

#[repr(C)]
pub struct YOutput {
    pub tag: c_char,
    pub len: c_int,
    // some fields omitted
}

An output value cell returned from yrs API methods. It describes a various types of data supported by yrs shared data types.

Since YOutput instances are always created by calling the corresponding yrs API functions, they eventually should be deallocated using youtput_destroy function.

Fields

tag: c_char

Tag describing, which value type is being stored by this input cell. Can be one of:

• Y_JSON_BOOL for boolean flags.
• Y_JSON_NUM for 64-bit floating point numbers.
• Y_JSON_INT for 64-bit signed integers.
• Y_JSON_STR for null-terminated UTF-8 encoded strings.
• Y_JSON_BUF for embedded binary data.
• Y_JSON_ARR for arrays of JSON-like values.
• Y_JSON_MAP for JSON-like objects build from key-value pairs.
• Y_JSON_NULL for JSON-like null values.
• Y_JSON_UNDEF for JSON-like undefined values.
• Y_TEXT for pointers to YText data types.
• Y_ARRAY for pointers to YArray data types.
• Y_MAP for pointers to YMap data types.
• Y_XML_ELEM for pointers to YXmlElement data types.
• Y_XML_TEXT for pointers to YXmlText data types.

len: c_int

Length of the contents stored by a current YOutput cell.

For Y_JSON_NULL and Y_JSON_UNDEF its equal to 0.

For Y_JSON_ARR, Y_JSON_MAP it describes a number of passed elements.

For other types it’s always equal to 1.
