Enum ExpressionRestriction 

pub enum ExpressionRestriction {
    None,
    NoStructLiteral,
}

Selects whether a header reserves an identifier’s following brace for its body.

Explicit delimiters establish ordinary expression boundaries; unary, binary, and closure expressions inherit the surrounding restriction.

Examples

use cel_parser::{CELParser, ExpressionRestriction, OpLookup};
let mut parser = CELParser::new(OpLookup::new());
parser.set_tokens("true {}".parse::<proc_macro2::TokenStream>().unwrap().into_iter());
parser.parse_expression_restricted(ExpressionRestriction::NoStructLiteral).unwrap();

Variants

None

Allows ordinary record literals.

NoStructLiteral

Leaves an unparenthesized identifier’s following brace to the enclosing grammar.
