}

An error resolving aliases or merge keys, or converting a node to a YamlValue that cannot hold it.

Variants

UndefinedAlias

An alias refers to an anchor that is not defined before it in the document.

Fields

alias: String

The anchor name the alias references, without the *.

RecursiveAlias

An alias refers to an anchor it is nested in, so expanding it would not terminate.

Fields

alias: String

The anchor name the alias references, without the *.

InvalidMergeOperand

A merge key (<<) operand is neither a mapping nor an alias to one.

Fields

operand: String

The source text of the offending operand.

DuplicateKey

A mapping has two equal keys, such as a and 'a', or a key and an alias to an equal node, so it cannot keep both values. A direct key shadowing a key from a merge key (<<) is not a duplicate. The members of a !!set and the keys of a !!omap have to be distinct too.

Fields

first: String

The source text of the key that was seen first.

second: String

The source text of the key that repeats it.

KeyCollision

Two distinct keys of a mapping have the same string form, such as the int 1 and the string '1', so they cannot both be kept in a YamlValue::Mapping. The same goes for the members of a YamlValue::Set and the keys of a YamlValue::OrderedMapping.

Fields

first: String

The source text of the key that was seen first.

second: String

The source text of the key that collides with it.

InvalidSetContent

The content of a !!set is not a mapping, so it has no members.

Fields

content: String

The source text of the content.

InvalidSetMember

A !!set member is not a scalar, so it cannot be kept in a YamlValue::Set.

Fields

member: String

The source text of the member.

NonNullSetValue

A !!set member has a value other than null, which a YamlValue::Set cannot keep.

Fields

member: String

The source text of the member.

value: String

The source text of its value.

InvalidPairsItem

An item of a !!omap or !!pairs sequence is not a mapping with a single entry.

Fields

tag: String

The tag of the sequence, !!omap or !!pairs.

item: String

The source text of the item.

InvalidPairsContent

The content of a !!omap or !!pairs is not a sequence, so it has no entries.

Fields

tag: String

The tag, !!omap or !!pairs.

content: String

The source text of the content.

UnresolvedAlias

YamlValue::cast met an alias, which it cannot resolve without the document’s anchors. YamlValue::from_document and DocumentResolvedExt::get_resolved resolve aliases.

Fields

alias: String

The anchor name the alias references, without the *.

ExtraNode

A document, key, value, sequence entry or tagged node holds more than one node, as in k: [q] x, which YAML does not allow but the parser accepts. A YamlValue can only keep one of them.

Fields

node: String

The source text of the node after the first.

Trait Implementations

impl Clone for ResolveError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Eq for ResolveError

impl Error for ResolveError

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 From<ResolveError> for YamlError

fn from(err: ResolveError) -> Self

Converts to this type from the input type.

impl PartialEq for ResolveError

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

Equality operator ==.

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

Inequality operator !=.
