formato desconhecido

Error message

formato desconhecido: {}

What it means

export() validates each requested output format against a fixed set (json, csv, srt, ass, vtt). Any format string outside that set reaches the catch-all `other =>` arm and bails with "formato desconhecido: {}". The library does not pre-validate formats, so the error surfaces only when rendering files.

Solutions

1. Use only the supported formats: json, csv, srt, ass, vtt (case-insensitive).
2. Fix the formats value in your config/CLI invocation — check for typos and stray whitespace.
3. Validate format strings against the allowed list before calling export().

Example fix

// before
let opts = ChatOpts { formats: vec!["txt".into()], ..Default::default() }; // bail: formato desconhecido: txt

// after
let allowed = ["json", "csv", "srt", "ass", "vtt"];
let formats: Vec<String> = vec!["txt".into()]
    .into_iter()
    .filter(|f| allowed.contains(&f.to_lowercase().as_str()))
    .collect();
let opts = ChatOpts { formats, ..Default::default() };

const SUPPORTED: [&str; 5] = ["json", "csv", "srt", "ass", "vtt"];
fn validate_formats(formats: &[String]) -> Result<(), String> {
    formats.iter()
        .find(|f| !SUPPORTED.contains(&f.to_lowercase().as_str()))
        .map(|f| Err(format!("formato desconhecido: {}", f)))
        .unwrap_or(Ok(()))
}

When it happens

Trigger: Calling export() with opts.formats containing anything other than "json", "csv", "srt", "ass", or "vtt" (case-insensitive) — e.g. "txt", "xml", "JSONL", or a locale-mangled value.

Common situations: Users typing an intuitive but unsupported extension like "text" or "ssa" in a config file; copying format names from another tool; passing a comma-separated string instead of individual format entries.

Understand the failure class

Background: Invalid enum value errors: "Unknown type", "Invalid scope", "must be one of" — when a string is not on the library's allowed list — this error's family across 23 libraries.
