Struct StepImagePlan 

pub struct StepImagePlan {
    pub n_tiles: usize,
    pub newline_mask: Vec<bool>,
}

Tiling plan for an image of (w, h): tile count, tiles per row (x_num), and the per-tile newline mask (vendor law: a newline after each full tile row, except a trailing one on the final tile). Derivable from HEADER dims alone, so the pad run and the request’s token price are known before any canvas expands.

Fields

n_tiles: usize

newline_mask: Vec<bool>

Implementations

impl StepImagePlan

pub fn n_rows(&self) -> usize

Trunk embedding rows this image occupies (pads only, not delimiters).

pub fn n_prompt_tokens(&self) -> usize

Prompt TOKENS the placeholder expansion renders (pads + delimiters + newlines).
