Struct ParseResult 

pub struct ParseResult {
    pub ast: Option<SpannedExpr>,
    pub macro_calls: MacroCalls,
    pub errors: Vec<ParseError>,
}

Result of parsing a CEL expression.

Supports error recovery: may return both an AST and errors. The AST may contain Expr::Error nodes where parsing failed. Includes macro_calls map for IDE features.

Fields

ast: Option<SpannedExpr>

The parsed AST, if any parsing succeeded. May contain Expr::Error nodes for unparseable sections. Macros (has, all, exists, exists_one, map, filter) are expanded inline.

macro_calls: MacroCalls

Map of comprehension/expansion IDs to original macro call expressions. Used for IDE features like hover to show the original source form.

errors: Vec<ParseError>

Any parse errors encountered.

Implementations

impl ParseResult

pub fn is_ok(&self) -> bool

Returns true if parsing completed without errors.

pub fn is_err(&self) -> bool

Returns true if there are any parse errors.

pub fn into_result(self) -> Result<SpannedExpr, Vec<ParseError>>

Converts to a Result, discarding partial AST on error.

pub fn unwrap_err(self) -> Vec<ParseError>

Unwraps the errors, panicking if there are none.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ParseResult

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