Struct EmbedCmd 

pub struct EmbedCmd { /* private fields */ }

Persistent-child-process adapter for a user-supplied embedder command. See the module docs for the protocol.

Implementations

impl EmbedCmd

pub fn new(cmd: &str, identity: EmbedderIdentity) -> Result<Self>

Spawn cmd (a shell-style command string: "python3 embedder.py" or "my-tool --model=foo") and prepare it to accept embed requests. The command is split by whitespace and single/double quotes — see [shlex_split] — and the program is launched directly, not through a shell. On Windows this means forward-slash paths work; on Unix it means no ~ expansion and no environment-variable substitution.

identity is the EmbedderIdentity this adapter will report; it is matched against the database’s manifest by crate::Mnemo::set_embedder. Pick values that describe what the child process actually computes — mismatched identities would corrupt recall silently.

pub fn with_timeout(self, timeout: Duration) -> Self

Replace the per-request timeout. See DEFAULT_EMBED_TIMEOUT.

Trait Implementations

impl Drop for EmbedCmd

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Embedder for EmbedCmd

fn identity(&self) -> EmbedderIdentity

This embedder’s observable identity (name, dims, normalize). Must be stable for the lifetime of the embedder — mnemo caches it on set_embedder and does not re-query per call.

fn embed(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>>

Embed texts, returning one vector per input in the same order. Caller-level errors (network failure for a hosted embedder, OOM in a local model) should bubble up as MnemoError::Invalid with a short message — the specific crypto / page errors in MnemoError are reserved for the engine’s own concerns.
