json_escape_into_buffer()

const char * esphome::captive_portal::json_escape_into_buffer ( std::span< char > buf, StringRef value )

inline

Copy value into buf, escaping the characters that cannot appear raw inside a JSON string literal.

Escapes " and \ along with the control characters below 0x20, using the short forms where JSON defines one and \u00XX otherwise. Bytes >= 0x20 are copied verbatim, so text containing valid UTF-8 survives intact. The result is always null terminated; anything that would not fit is dropped rather than written partially. Returns buf so the call can be used directly as an argument.

To size buf so that no input is ever dropped, allow JSON_ESCAPE_MAX_EXPANSION bytes per input byte plus one for the null terminator.
