Struct QueryWarning 

#[non_exhaustive]
pub struct QueryWarning {
    pub severity: WarningSeverity,
    pub function: String,
    pub argument: usize,
    pub kind: String,
    pub count: u64,
    pub sample: Option<String>,
    pub hint: String,
    pub message: String,
}

One diagnostic about a query evaluation: a counted class of type errors, or a hint. Returned by eval_query_with_warnings.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

severity: WarningSeverity

function: String

The SPARQL function name, upper-case ("CONTAINS"), or the operator’s spelling for an operator: + - * /, = != < <= > >=, IN.

argument: usize

1-based argument position the problem is about (0 = not argument-specific). For an operator, 1 is the left operand and 2 the right one.

kind: String

What the argument was: iri, blank-node, quoted-triple, numeric, typed-literal, string, language-tagged, invalid-number, language-mismatch, unbound, invalid-regex, not-a-datetime, division-by-zero (argument 2 of /), or case-sensitive for the hint.

count: u64

How many evaluations raised this error (an evaluation is one row reaching the expression; LIMIT / ASK stop early, so this is not a data count).

sample: Option<String>

The first offending value, truncated to 80 characters (plus …).

hint: String

A short, actionable suggestion.

message: String

The whole warning as one plain-language sentence.
