pub enum ParseError {
    Grammar(Language),
    NoTree,
    Syntax(Vec<SyntaxIssue>),
    Unsupported {
        kind: String,
        span_start: usize,
    },
    InvalidDeclaration(String),
}

Header parsing failure.

Variants

Grammar(Language)

The selected grammar could not be installed.

NoTree

Tree-sitter could not produce a tree.

Syntax(Vec<SyntaxIssue>)

Concrete syntax errors were found.

Unsupported

A syntactically valid construct cannot be represented by the typed AST.

Fields

kind: String

Tree-sitter construct name.

span_start: usize

Starting byte offset.

InvalidDeclaration(String)

A declaration was syntactically present but not structurally valid.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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.
