pub struct StaticEmbedder { /* private fields */ }Expand description
Model2Vec / potion-style static token-pooled embedder.
Holds a precomputed token -> vector table loaded from a vendored
asset. Embedding is tokenize -> lookup each token's vector -> mean -> L2-normalize, with NO neural-network forward pass — that is the entire
point of static embeddings (microsecond latency, tiny footprint).
§Asset format (intentionally simple + dependency-free)
The asset directory contains static-embeddings.json:
{ "dim": 8, "vectors": { "rate": [...8 floats...], "limit": [...] } }Tokens are the same word tokens [tokenize::word_tokens] produces, so a
distilled potion table can be exported into this shape offline. A real
.safetensors loader (via model2vec-rs) can be added behind a feature
later without touching this trait or the JSON fallback — both satisfy
the same token -> vector contract.
Implementations§
Source§impl StaticEmbedder
impl StaticEmbedder
Sourcepub fn from_asset_dir(asset_dir: &Path) -> Result<Self, String>
pub fn from_asset_dir(asset_dir: &Path) -> Result<Self, String>
Resolve and load static-embeddings.json under asset_dir.
Returns Err (so the caller can fall back to lexical) when the
directory or file is missing, unreadable, malformed, or empty. This
is the sandbox/settings-aware degradation contract: a missing asset
never panics and never blocks — it just selects the lexical floor.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
