ReservedSchemaKey

Schema declares a regular section or metadata field whose key collides with an engine-invariant key. The reserved set covers section key relationships (the parser’s auto-managed ## Relationships section) and metadata field key type (the engine-set frontmatter type discriminator).

Fields

type_name: String

kind: &'static str

offending_key: String

reserved_keys: Vec<String>

InvalidCrossMemToSchema

A cross_mem_relationships: entry’s to_schema: field is not a bare schema name. Cross-mem eligibility is name-based — versioned (software@1.0.0) and range (software@^1.0) forms are refused so a version component can never silently re-enter the eligibility path.

Fields

value: String

reason: String

DuplicateCrossMemToSchema

Two cross_mem_relationships: entries declare the same to_schema:. A schema declares each target-schema at most once — the second entry would otherwise silently shadow or split the vocabulary.

Fields

to_schema: String

UndeclaredCrossMemSourceType

A cross_mem_relationships[].definitions[*].source_types entry references a type name not declared in the source schema’s types list. Source types belong to the source schema’s namespace; unknown names raise this error at load time. (Target types are accepted as opaque strings — they belong to the target schema’s namespace, which is not in scope here.)

Fields

to_schema: String

relationship: String

reference: String

declared: Vec<String>

AliasTargetRelTypeNotDeclared

The schema’s alias_target_rel_type: pointer names a rel-type not declared in relationships.definitions. Surfaces at schema-load time so the alias-synthesis pass can trust the pointer is resolvable at every later mutation call.

Fields

schema: String

target: String

declared: Vec<String>

Trait Implementations

impl Debug for SchemaLoadError

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

Formats the value using the given formatter.

impl Display for SchemaLoadError

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

Formats the value using the given formatter.

impl Error for SchemaLoadError

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.
