Enum ArgOr 

pub enum ArgOr<V> {
    Arg(usize),
    Value(V),
}

Matches either an extracted bind-parameter placeholder (Expr::Arg, emitted by SQL drivers after parameter extraction) at a specific position, or an inline Expr::Value matching the contained pattern (emitted by non-SQL drivers like DynamoDB).

Use this when a single assertion needs to cover both representations:

let val = if test.capability().sql {
    ArgOr::Arg(0)
} else {
    ArgOr::Value(1i64)
};
assert_struct!(op, ..., rows: [=~ (Any, Any, val)]);

Variants

Arg(usize)

Matches Expr::Arg(_) whose position equals the given index.

Value(V)

Matches Expr::Value(_) using the inner pattern via Like<V>.

Trait Implementations

impl<V> Like<ArgOr<V>> for Expr

where Expr: Like<V>,

fn like(&self, pattern: &ArgOr<V>) -> bool

Returns true if self matches the pattern other.
