Trait Embedder 

pub trait Embedder {
    // Required methods
    fn dimension(&self) -> usize;
    fn embed(&self, text: &str) -> Result<Vec<f32>, EmbedError>;
}

Turns text into a fixed-dimension embedding vector.

Required Methods

fn dimension(&self) -> usize

Embedding dimension produced by Embedder::embed.

fn embed(&self, text: &str) -> Result<Vec<f32>, EmbedError>

Embed text into a vector of length Embedder::dimension.

Errors

Returns EmbedError if the backend cannot produce an embedding.

Dyn Compatibility

This trait is dyn compatible.

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