Attribute Macro rust_sitter::prec

#[prec]

Defines a precedence level for a non-terminal that has no associativity.

This annotation takes a single, unnamed parameter, which specifies the precedence level. This is used to resolve conflicts with other non-terminals, so that the one with the higher precedence will bind more tightly (appear lower in the parse tree).

Example

#[rust_sitter::prec(1)]
PriorityExpr(Box<Expr>, Box<Expr>)
