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 for folder entries; logs collisions.

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

Current size in bytes, or None if there is no such asset (or its file vanished).

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

Copy bytes starting at offset into dst. Returns bytes copied (0 at or past the end), or None if there is no such asset. Short reads (a file that shrank) return what was available; I/O errors end the read early.

pub fn names(&self) -> Vec<String>

All asset names, sorted.

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.
