Struct UpdatePermission 

#[non_exhaustive]
pub struct UpdatePermission {
    pub columns: ColumnSet,
    pub filter: Value,
    pub check: Value,
    pub set: HashMap<String, Value>,
}

Which rows a role may change, which columns of them, and what the result has to satisfy.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

columns: ColumnSet

The columns the role may write.

filter: Value

Which rows may be changed, read before the change.

check: Value

What they must satisfy afterwards. Absent means the filter stands in, which is Hasura’s rule: a row you may change is a row you may change into something you may still change.

set: HashMap<String, Value>

Columns forced to a fixed value on every update, whatever the request asked for. Hasura’s set, used for things like an updated-at stamp.
