Function ruma::user_id::localpart_is_fully_conforming
source · pub fn localpart_is_fully_conforming(localpart: &str) -> Result<bool, Error>
Expand description
Check whether the given user id localpart is valid and fully conforming
Returns an Err
for invalid user ID localparts, Ok(false)
for historical user ID localparts
and Ok(true)
for fully conforming user ID localparts.
With the compat
feature enabled, this will also return Ok(false)
for invalid user ID
localparts. User IDs that don’t even meet the historical user ID restrictions exist in the wild
due to Synapse allowing them over federation. This will likely be fixed in an upcoming room
version; see MSC2828.
