Struct SecurityContextHashInput 

pub struct SecurityContextHashInput<'a> {
    pub user_id: &'a str,
    pub roles: &'a [&'a str],
    pub tenant_id: Option<&'a str>,
    pub scopes: &'a [&'a str],
}

Borrowed view of the identity fields used for context hashing.

All fields that determine who a user is from an RLS perspective are included. Fields that are per-request metadata (request_id, ip_address) are intentionally excluded so that two requests from the same principal share the same hash.

Fields

user_id: &'a str

User identifier (from JWT sub claim).

roles: &'a [&'a str]

User’s roles.

tenant_id: Option<&'a str>

Tenant/organisation identifier.

scopes: &'a [&'a str]

OAuth/permission scopes.
