Trait TryIntoContents

Source

pub trait TryIntoContents {
    // Required method
    fn try_into_contents(self) -> Result<Vec<Content>, Error>;

    // Provided method
    fn try_into_cached_content_for(
        self,
        model_name: &str,
    ) -> Result<CachedContent, Error>
       where Self: Sized { ... }
}

Expand description

Fallible conversion to multiple Content items

Use this for types that need to perform validation or conditional construction of content. Prefer IntoContents for infallible conversions.

§Examples

Custom serialization with media attachment:

use google_ai_rs::{TryIntoContents, Content, Error, IntoParts as _, Part};

struct UserInput {
    message: String,
    media: Option<MediaAttachment>
}

impl TryIntoContents for UserInput {
    fn try_into_contents(self) -> Result<Vec<Content>, Error> {
        let mut parts = self.message.into_parts();

        if let Some(media) = self.media {
            let part = match media {
                MediaAttachment::Image(data) => Part::blob("image/png", data),
                MediaAttachment::VoiceNote(data) => Part::blob("audio/wave", data),
            };
            parts.push(part);
        }
        
        Ok(vec![Content::from(parts)])
    }
}
