Struct ParseResult 

pub struct ParseResult {
    pub file: File,
    pub diagnostics: Vec<ParseDiagnostic>,
    pub status: ParseStatus,
    pub terminal_error: Option<Error>,
    pub syntax_facts: SyntaxFacts,
}

The result of parsing a script, including any recovery diagnostics and syntax facts collected along the way.

Fields

file: File

Parsed syntax tree for the file.

diagnostics: Vec<ParseDiagnostic>

Recovery diagnostics emitted while producing the AST.

status: ParseStatus

High-level parse status.

terminal_error: Option<Error>

Terminal parse error, when recovery could not continue.

syntax_facts: SyntaxFacts

Additional syntax facts collected during parsing.

Implementations

impl ParseResult

pub fn is_ok(&self) -> bool

Returns true when the parse completed without recovery diagnostics.

pub fn is_err(&self) -> bool

Returns true when the parse produced recovery diagnostics or a terminal error.

pub fn strict_error(&self) -> Error

Convert this result into a strict parse error.

If recovery diagnostics exist but no terminal error was recorded, the first recovery diagnostic is converted into an Error.

pub fn unwrap(self) -> Self

Return the parse result when it is clean, otherwise panic with the strict error.

pub fn expect(self, message: &str) -> Self

Return the parse result when it is clean, otherwise panic with message.

pub fn unwrap_err(self) -> Error

Return the strict parse error when the result is not clean, otherwise panic.

pub fn expect_err(self, message: &str) -> Error

Return the strict parse error when the result is not clean, otherwise panic with message.

Trait Implementations

impl Clone for ParseResult

fn clone(&self) -> ParseResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseResult

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

Formats the value using the given formatter.
