Enum PackValidationError 

#[non_exhaustive]
pub enum PackValidationError {
    DuplicateSymlinkDst {
        dst: String,
        first: usize,
        second: usize,
    },
    GraphCycle {
        chain: Vec<String>,
    },
    DependsOnUnsatisfied {
        pack: String,
        required: String,
    },
}

Errors raised by plan-phase validators.

Marked #[non_exhaustive] so future slices (slices 3–6) can add variants without breaking downstream match arms.

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.

DuplicateSymlinkDst

Two symlink actions within the same pack resolve to the same literal dst string. first and second are indices in the flattened action-walk order (see PackManifest::iter_all_symlinks).

Fields

dst: String

Literal dst string (pre-expansion).

first: usize

Global index of the earlier action.

second: usize

Global index of the later action.

GraphCycle

A cycle was detected in the assembled pack graph. chain lists the pack names from the outermost node down to the recurrence.

Fields

chain: Vec<String>

Ordered chain of pack names that forms the cycle.

DependsOnUnsatisfied

A depends_on entry could not be resolved against any node in the walked graph.

Fields

pack: String

Name of the pack that declared the dependency.

required: String

The unresolved depends_on entry (a pack name or url).

Trait Implementations

impl Clone for PackValidationError

fn clone(&self) -> PackValidationError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PackValidationError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PackValidationError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PackValidationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for PackValidationError

fn eq(&self, other: &PackValidationError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
