Variants

InvalidPath

A path cannot identify a canonical file for its declared role.

Fields

role: PackPathRole

path: String

message: String

InvalidPackageSpec

A package value cannot be represented as a canonical package specification.

Fields

spec: String

message: String

InvalidPackageRequirement

A Package Requirement has a malformed or unsupported tree identity.

Fields

spec: String

MismatchedEmbeddedPackageIdentity(String)

Embedded package bytes disagree with their declared tree identity.

ArchiveEntryNameTooLong

A contained path cannot fit in ZIP’s filename field after adding its role prefix.

Fields

role: PackPathRole

path: String

CanonicalArchiveEntryCollision

Distinct archive entries identify one canonical contained file.

Fields

canonical: String

first_entry: String

second_entry: String

PathTreeConflict

One file path is an ancestor of another file path in the same tree.

Fields

ancestor: String

ancestor_role: PackPathRole

descendant: String

descendant_role: PackPathRole

PackagePathTreeConflict

One package file path is an ancestor of another file path in that package.

Fields

package: String

ancestor: String

ancestor_role: PackPathRole

descendant: String

descendant_role: PackPathRole

PackageRoleConflict(String)

A package was declared both vendored and unvendored.

UndeclaredPackageData(String)

Package bytes exist without a matching vendored declaration.

MissingVendoredPackageData(String)

A vendored package declaration has no contained bytes.

ReservedFontPath

A font declaration uses an archive path reserved for another role.

Fields

path: String

conflicting_role: PackPathRole

MissingFontData(String)

A font declaration has no contained bytes.

InvalidFontData

Contained font bytes do not contain the declared face.

Fields

path: String

index: u32

InvalidExternalFontIdentity

An external font declaration has no valid exact container identity.

Fields

path: String

MismatchedEmbeddedFontIdentity

Embedded font bytes disagree with their declared exact identity.

Fields

path: String

InconsistentFontContainer

Faces from one exact container disagree about its length or fulfillment role.

Fields

path: String

ExternalFontHasContainedData

An externally fulfilled declaration also has bytes in the Pack.

Fields

path: String

DuplicateFontFace

The same contained font face was declared more than once.

Fields

path: String

index: u32

MissingEntrypoint(String)

The declared entrypoint is not present among the packed project files.

Trait Implementations
