Enum MaterialOverviewKind 

#[non_exhaustive]
pub enum MaterialOverviewKind {
    Digital,
    Physical {
        identifier: Option<String>,
        quantity: Option<u32>,
    },
}

Kind of material in MaterialOverview. Mirrors the structural distinction of the IR’s MaterialKind without the load-time implementation detail (file sources).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Digital

File-backed digital material.

Physical

Tangible item with optional identifier and quantity.

Fields

identifier: Option<String>

Human-readable identifier (e.g. serial number).

quantity: Option<u32>

Item count for checklist rendering.

Implementations

impl MaterialOverviewKind

pub fn physical(identifier: Option<String>, quantity: Option<u32>) -> Self

Construct a MaterialOverviewKind::Physical with optional identifier and quantity. Needed because the variant is reachable only via the constructor when the enum stays #[non_exhaustive].
