PackageDoesNotLoad

The package fails to load even under the tolerant sealed-style read that translates every retired key — so something other than a retired key is wrong, and rewriting spellings would not help.

Fields

source: SchemaLoadError

RewriteLeavesViolations

The rewrite still refuses under the strict authoring read. The rewriter reached every key it can (block-style, unquoted); what remains is a spelling it does not edit.

Fields

source: SchemaLoadError

Unfaithful

The rewrite loads but resolves differently from the loader’s own translation of the original — an internal defect, never an authoring problem. Nothing is written.

detail: String

Trait Implementations

impl Debug for MigrateError

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

Formats the value using the given formatter.

impl Display for MigrateError

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

Formats the value using the given formatter.

impl Error for MigrateError

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.
