cannot convert to StrandBuf

Error message

cannot convert to StrandBuf

What it means

Thrown by the by-value `TryFrom<Data> for StrandBuf` when the value cannot become a strand (string-like buffer). Accepted variants are `String`, `Path`, and `Bytes`; everything else bails with "cannot convert to StrandBuf".

Solutions

1. Match the variant and stringify manually where appropriate (e.g. format integers/numbers with `to_string()`).
2. Fix the producer to emit `Data::String`/`Data::Path`/`Data::Bytes`.
3. Convert `Data::Url` via its strand representation before wrapping in StrandBuf if URLs should be accepted.

Example fix

// before
let s: StrandBuf = data.try_into()?;
// after
let s: StrandBuf = match data {
    d @ (Data::String(_) | Data::Path(_) | Data::Bytes(_)) => d.try_into()?,
    Data::Integer(i) => i.to_string().into(),
    other => bail!("cannot stringify {other:?}"),
};

fn is_strand_like(data: &Data) -> bool {
    matches!(data, Data::String(_) | Data::Path(_) | Data::Bytes(_))
}

fn to_strand(data: Data) -> Option<StrandBuf> {
    match data {
        Data::String(_) | Data::Path(_) | Data::Bytes(_) => StrandBuf::try_from(data).ok(),
        _ => None,
    }
}

match StrandBuf::try_from(data) {
    Ok(s) => use_strand(s),
    Err(e) => log::warn!("expected text-like value: {e}"),
}

When it happens

Trigger: `StrandBuf::try_from(data)` where `data` is `Data::Bool`, `Data::Integer`, `Data::Number`, `Data::Url`, `Data::Dict`, or `Data::Any`.

Common situations: Rendering or logging a fetched value that turned out to be numeric/boolean, or a Lua script passing `nil`/table where a string was required.
