Struct Loader 

pub struct Loader<'a> { /* private fields */ }

Decodes one model’s textures: looks pictures up next to the model, keeps the decoded total within BUDGET and decodes each file or embedded picture once.

Implementations

impl<'a> Loader<'a>

pub fn new(side: Side<'a>) -> Loader<'a>

pub fn with_budget(side: Side<'a>, budget: usize) -> Loader<'a>

A loader with its own byte budget.

pub fn for_map<T>(&mut self, read: impl FnOnce(&mut Self) -> T) -> T

Runs read, a read of a normal, bump or emissive map: it may take only half of the bytes still free.

pub fn left(&self) -> usize

Bytes of RGBA still free.

pub fn file(&mut self, path: &str) -> Option<Arc<Image>>

The picture a model names by path (see candidates).

pub fn file_in(&mut self, dir: &str, path: &str) -> Option<Arc<Image>>

The picture named by path in a file that sits in the folder dir (relative to the model, as an MTL library in a subfolder): tried there first, then as Loader::file would.

pub fn embedded(&mut self, name: &str, data: &[u8]) -> Option<Arc<Image>>

A picture whose file bytes are data (embedded in the model, or read by Loader::file), called name.
