Struct Config 

pub struct Config {
    pub embedding_dim: usize,
    pub window_size: usize,
    pub negative_samples: usize,
    pub epochs: usize,
    pub learning_rate: f32,
    pub min_learning_rate: f32,
    pub min_count: usize,
    pub subsample_threshold: f64,
    pub model: ModelType,
    pub num_threads: usize,
    pub seed: u64,
}

Full training configuration.

All fields have sensible defaults via Config::default().

Fields

embedding_dim: usize

Dimensionality of word embeddings (typical: 50–300).

window_size: usize

Half-width of the context window (words on each side of target).

negative_samples: usize

Number of negative samples per positive pair (typical: 5–20).

epochs: usize

Full passes over the corpus.

learning_rate: f32

Initial learning rate (decays linearly to min_learning_rate).

min_learning_rate: f32

Floor for decayed learning rate.

min_count: usize

Discard words appearing fewer than this many times.

subsample_threshold: f64

Frequent-word subsampling threshold (Mikolov et al. suggest 1e-3 – 1e-5).

model: ModelType

Architecture choice.

num_threads: usize

Rayon thread count (0 = use all logical cores).

seed: u64

RNG seed for reproducibility.

Implementations

impl Config

pub fn validate(&self) -> Result<(), String>

Validate configuration, returning an error message if invalid.

use word2vec::Config;
let cfg = Config { embedding_dim: 0, ..Config::default() };
assert!(cfg.validate().is_err());

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Sensible defaults matching the original word2vec paper.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
