Struct parse_mediawiki_sql::field_types::PageRestrictionsOld

pub struct PageRestrictionsOld<'a>(pub BTreeMap<PageAction<'a>, Vec<ProtectionLevel<'a>>>);

Represents page_restrictions, an outdated field of the page table containing a string representing a map from action to the groups that are allowed to perform that action.

Here the action is represented by PageAction and the protection level by ProtectionLevel. This field was replaced by the page_restrictions table in MediaWiki 1.10, but is still used by the software if a page’s restrictions have not been changed since MediaWiki 1.10 came out.

The string is in the following format, at least on the English Wiktionary:

# level on its own seems to be shorthand for both "edit" and "move"
"" | level | spec (":" spec)*
spec: action "=" level
# "" means no restrictions
level: "autoconfirmed" | "templateeditor" | "sysop" | ""
action: "edit" | "move" | "upload"

However, spec is treated as having the following format, because the documentation for this field gives the example edit=autoconfirmed,sysop:move=sysop with multiple protection levels per action:

spec: action "=" level ("," level)*

The example given is nonsensical because users in the sysop group have all the rights of users in the autoconfirmed group, and neither English Wikipedia nor English Wiktionary have any page_restrictions strings in this format, but perhaps these types of protection strings have existed in the past or exist now on other wikis.
