Struct PreprocessConfig 

pub struct PreprocessConfig {
    pub image_size: usize,
    pub patch_size: usize,
    pub mean: [f32; 3],
    pub std: [f32; 3],
}

How an image is prepared for a specific vision tower.

Fields

image_size: usize

Side length of the square canvas the tower expects, in pixels.

patch_size: usize

Side length of one square patch. Must divide Self::image_size — a tower’s position-embedding table has exactly (image_size / patch_size)² entries, so a non-dividing pair describes a model that cannot exist.

mean: [f32; 3]

std: [f32; 3]

Implementations

impl PreprocessConfig

pub fn grid(&self) -> usize

Patches per side of the canvas.

pub fn n_patches(&self) -> usize

Total patches — the sequence length the vision tower sees.

pub fn patch_dim(&self) -> usize

Flattened length of one patch: patch · patch · 3.

Trait Implementations

impl Clone for PreprocessConfig

fn clone(&self) -> PreprocessConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PreprocessConfig

impl Debug for PreprocessConfig

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

Formats the value using the given formatter.

impl Default for PreprocessConfig

fn default() -> Self

SigLIP-style 512px canvas with 16px patches — SmolVLM’s shape.

A default is offered only so tests and callers have a sane starting point; a real run must take these from the loaded model’s metadata, because guessing them wrong produces plausible-looking garbage rather than an error.

impl PartialEq for PreprocessConfig

fn eq(&self, other: &PreprocessConfig) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
