Function get_field_equality_expr

Source 
fn get_field_equality_expr(cx: &ExtCtxt<'_>, field: &FieldInfo) -> P<Expr>
Expand description

Generates an equality comparison expression for a single struct or enum field.

This function produces an AST expression that compares the self and other values for a field using ==. It removes any leading references from both sides for readability. If the field is a block expression, it is wrapped in parentheses to ensure valid syntax.

ยงPanics

Panics if there are not exactly two arguments to compare (should be self and other).
