Struct FieldAuthzRequest 

#[non_exhaustive]
pub struct FieldAuthzRequest<'a> {
    pub principal: &'a SecurityContext,
    pub type_name: &'a str,
    pub field_name: &'a str,
    pub parent: Option<&'a Value>,
    pub arguments: Option<&'a Value>,
}

A field-level authorization request handed to a FieldAuthorizer.

Carries the principal, the field being resolved (its GraphQL type and name), the full parent row it is being projected from, and the field’s GraphQL arguments — the exact inputs a static scope check lacks.

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.

principal: &'a SecurityContext

The authenticated principal making the request.

type_name: &'a str

The GraphQL type name that owns the field (e.g. "User").

field_name: &'a str

The field name being authorized (e.g. "email").

parent: Option<&'a Value>

The full row/object the field is projected from, when available.

This is the complete fetched row (not just the selected fields), so a policy may key on columns the client did not select (e.g. an owner_id used to decide ownership). None only on paths where no row context exists.

arguments: Option<&'a Value>

The field’s GraphQL arguments, when present.
