Structural problems found while building or validating a component graph.

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.

MissingTarget

An INCL payload names no DIRM component.

Fields

source: String

Component that carried the INCL chunk.

target: String

Trimmed component identity named by the INCL chunk.

DuplicateIdentity

More than one DIRM entry declares the same identity.

Fields

id: String

The duplicated DIRM identity.

InvalidComponentType

A component FORM type is unknown or disagrees with its DIRM entry.

Fields

id: String

Identity from the DIRM entry.

form: [u8; 4]

Embedded FORM type.

Cycle

A directed INCL cycle, with the first node repeated at the end.

Fields

path: Vec<String>

Component identities forming the directed cycle.

Malformed(String)

The DJVM container or its DIRM/component bodies could not be parsed.
