Enum PreprocessOutcome 

pub enum PreprocessOutcome {
    Skipped,
    Replaced {
        text: String,
        vl_key: String,
    },
    Failed {
        reason: String,
    },
}

Outcome of a preprocessing attempt.

Variants

Skipped

Preprocessing did not run — feature disabled, main provider already accepts images, or no images attached. Caller must use the original (caption, images) tuple unchanged.

Replaced

VL call succeeded. text is the raw VL output (no wrapping); vl_key is the provider key used (so the caller can show “by {model}” in the splice wrapper). Caller is responsible for splicing both into the user message — recommended shape: format!("{caption}\n\n[图片内容（由 {vl_key} 识别）]\n{text}") — and clearing the images vec.

Fields

text: String

vl_key: String

Failed

VL call failed (provider missing, network error, timeout, empty response). reason is intended for AgentEvent::Warning. Caller should append "\n\n[图片识别失败]" to the user message and clear images so the turn proceeds with a useful placeholder.

Fields

reason: String
