Enum QueryError

pub enum QueryError {
    InvalidLanguage(LanguageError),
    InvalidInput,
    ExpectedMapping(String),
    ExpectedList(usize),
    ExhaustedMapping(String),
    ExhaustedList(usize, usize),

}

Possible errors when performing YAML path queries.

Variants

InvalidLanguage(LanguageError)

The tree-sitter backend couldn’t accept the YAML grammar.

InvalidInput

The user’s input YAML is malformed.

ExpectedMapping(String)

The query expects a key at a given point, but the input isn’t a mapping.

ExpectedList(usize)

The query expects a list index at a given point, but the input isn’t a list.

ExhaustedMapping(String)

The query expects the given key in a mapping, but the mapping doesn’t have that key.

ExhaustedList(usize, usize)

The query expects the given list index, but the list isn’t the right size.

UnexpectedNode(String)

The YAML syntax tree wasn’t structured the way we expect.

MissingChild(String, String)

The YAML syntax tree is missing an expected named child node.

MissingChildField(String, &'static str)

The YAML syntax tree is missing an expected named child node with the given field name.

Other(String)

Any other query error that doesn’t fit cleanly above.

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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<LanguageError> for QueryError

fn from(source: LanguageError) -> Self

Converts to this type from the input type.
