Reads the current plain-text content of a pad. Pads are ephemeral: they are lost when the Rustpad server restarts and after 24 hours without an open connection. An empty result is ambiguous: Rustpad cannot distinguish an empty pad from one that never existed or has expired.

Fetches metadata about a pad over the collaboration socket: content length, revision, editor language and the users who have it open right now. Pads are ephemeral: they are lost when the Rustpad server restarts and after 24 hours without an open connection.

Reads the Rustpad server statistics: start time, number of documents currently held in memory, and the number persisted in the database (0 when the instance runs without persistence).

Creates a pad, optionally with initial content and an editor language, and returns its shareable URL. Without an id a random one is generated. Pads are ephemeral: they are lost when the Rustpad server restarts and after 24 hours without an open connection. Anyone who knows the URL can read and edit the pad.

Replaces the entire content of a pad. Replacing a non-empty pad requires confirmation: call once to receive a token, then again with that token. For targeted changes prefer replace_in_document, which leaves concurrent edits elsewhere in the pad intact.

Appends text to the end of a pad, leaving everything else — including concurrent edits — untouched. The text is appended verbatim; include a leading newline to start a new line.

Replaces an exact string in a pad with another. Only the matched ranges are edited, so concurrent edits elsewhere in the pad survive. By default the search string must match exactly once; set replace_all to change every occurrence.

Sets the syntax-highlighting language of a pad (Monaco language id, e.g. "markdown", "javascript", "rust"). Last writer wins; the change is visible to everyone who has the pad open.
