    fn embed<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,

    fn dim(&self) -> usize;
    fn handle(&self) -> &str;
}

Producer of fixed-dimension float vectors for input text. Batched.

Adapters MUST:

• Return exactly inputs.len() vectors, in the same order.
• Each vector MUST be exactly dim() long.
• Treat empty inputs as Ok(Vec::new()) (no provider call).

Required Methods

fn embed<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, inputs: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Result<Vec<Vec<f32>>, EmbedError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Embed a batch of strings. Empty input → empty output, no provider call.

fn dim(&self) -> usize

Output dimensionality. Constant per adapter instance.

fn handle(&self) -> &str

Human-readable identifier, e.g. "gemini:text-embedding-004". Used in logs and to tag stored vectors so the schema can detect a dim change after a model swap.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
