unable to parse as integer

Error message

unable to parse as integer: {0}

What it means

`IdParsingError` in influxdb3_id is thrown when a string cannot be parsed into the integer backing a catalog ID type (e.g., u32/u64 identifiers). It wraps `ParseIntError` via `#[from]` and renders as "unable to parse as integer: {0}".

Solutions

1. Confirm the identifier is a plain numeric ID in the expected type's range
2. Trim whitespace/URL-encoding from the input string before parsing
3. Use the ID exactly as returned by the API rather than reconstructing it

Example fix

// before
let id: NodeId = "3f8a2b".parse()?;
// after
let id: NodeId = "42".parse()?;

// rust
fn is_valid_id(s: &str) -> bool {
    !s.trim().is_empty() && s.trim().chars().all(|c| c.is_ascii_digit())
}

// rust
fn parse_node_id(s: &str) -> Option<NodeId> {
    s.trim().parse::<NodeId>().ok()
}

// rust
match "42".parse::<NodeId>() {
    Ok(id) => use_id(id),
    Err(e) => eprintln!("bad id input: {e}"),
}

When it happens

Trigger: Deserializing or parsing a catalog ID from a string (HTTP path parameter, config, persisted catalog data) that is not a valid integer for the target type.

Common situations: Passing a UUID or non-numeric identifier where a numeric catalog ID is expected; empty string; integer overflow beyond the backing type's range (e.g., value > u32::MAX).

Understand the failure class

Background: "invalid id" errors: invalid identifier format — why libraries reject IDs before lookup, and how to fix them — this error's family across 37 libraries.

• Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
