```

Validate this predicate for one fixed-width integer kind.

# Errors

Returns [`FilterExpressionErrorKind::UnknownOperator`] for a
non-integer family, [`FilterExpressionErrorKind::InvalidStructure`]
for an invalid equality shape, or
[`FilterExpressionErrorKind::InvalidLiteral`] for signedness or
range mismatches.

The [`crate::query::Filterable`] example executes this method for
both signed and unsigned fields in a hand-written expansion.
