Struct Assets 

pub struct Assets { /* private fields */ }

Implementations

impl Assets

pub fn new() -> Assets

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn insert_memory(&mut self, name: &str, bytes: Vec<u8>)

Asset from memory (overrides any entry with the same name).

pub fn insert_file(&mut self, name: &str, path: &Path) -> Result<(), String>

Asset backed by a file, opened now and read on demand (overrides any entry with the same name).

pub fn add_dir( &mut self, prefix: Option<&str>, dir: &Path, ) -> Result<usize, String>

Expose every regular file under dir (recursively), named [prefix/]relative/path. Existing names are kept (explicit assets win). Returns the number of files added. Call Assets::finish afterwards.

pub fn finish(&mut self)

Build the case-insensitive index and the sorted name list; logs collisions.

pub fn get(&self, name: &str) -> Option<Asset<'_>>

Look an asset up (exact name, then case-insensitively among folder entries).

pub fn size(&self, name: &str) -> Option<u64>

Current size in bytes, or None if there is no such asset.

pub fn read_at(&self, name: &str, offset: u64, dst: &mut [u8]) -> Option<usize>

Copy bytes starting at offset into dst (see Asset::read_at), or None if there is no such asset.

pub fn names(&self) -> &[String]

All asset names, sorted (by UTF-8 bytes).

Trait Implementations

impl Default for Assets

fn default() -> Self

Returns the “default value” for a type.

impl From<HashMap<String, Vec<u8>>> for Assets

fn from(map: HashMap<String, Vec<u8>>) -> Assets

Converts to this type from the input type.
