Struct IncorrectKind 

pub struct IncorrectKind<'tree> {
    pub node: UntypedNode<'tree>,
    pub kind: &'static str,
}

Error when attempting to wrap a node of the wrong kind

Fields

node: UntypedNode<'tree>

Node attempted to be wrapped

kind: &'static str

Expected node kind

Implementations

impl<'tree> IncorrectKind<'tree>

pub fn new<Node>(node: Node<'tree>) -> IncorrectKind<'tree>

where Node: Node<'tree>,

Create an error for another tree-sitter node when a typed node was expected.

Node is the type of node that was expected.

pub fn actual_kind(&self) -> &'static str

The actual kind of node that we encountered, not kind which is the one we expected.

pub fn is_error(&self) -> bool

Is the actual node an error?

pub fn is_missing(&self) -> bool

Is the actual node missing?

pub fn cause(&self) -> IncorrectKindCause

Whether the node is an error, missing, extra, or is just some other node of unexpected kind.

Typically IncorrectKind comes from an error or missing node. The latter cases (extra or or other) are more likely to be a bug in the code or the tree-sitter grammar, not the parsed AST.

pub fn with_source_range(&self) -> impl Display

Print an error message for this with the source range.

The default impl Display prints an error message without the source range.

Trait Implementations

impl<'tree> Clone for IncorrectKind<'tree>

fn clone(&self) -> IncorrectKind<'tree>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'tree> Debug for IncorrectKind<'tree>

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

Formats the value using the given formatter.

impl Display for IncorrectKind<'_>

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

Formats the value using the given formatter.

impl Error for IncorrectKind<'_>

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<'tree> Hash for IncorrectKind<'tree>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tree> PartialEq for IncorrectKind<'tree>

fn eq(&self, other: &IncorrectKind<'tree>) -> 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.
