Struct FileRef 

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

A file loaded from ROM or data dir into the memory.

Returned by [rom::load] and [data::load] which requires a pre-allocated buffer of the right size. If the file size is deterimed dynamically, you might want to use [rom::load_buf] and [data::load_buf] instead (which will take care of the dynamic allocation).

Implementations

impl<'a> FileRef<'a>

pub unsafe fn from_bytes(b: &'a [u8]) -> Self

Construct [File] from raw bytes.

The main purpose of this function is to support convering [File] to and from “basic” types, which might be required for implementing some language interpreters (Lua, Python, etc) for Firefly in Rust.

Safety

This function allows bypassing type safety and constructing Image and Font in runtime. Don’t do that. Relying on internal representation of file formats might make your app incompatible with future Firefly runtimes. If you need to modify an in-memory image, use Canvas instead.

pub fn into_font(self) -> FontRef<'a>

pub fn into_image(self) -> ImageRef<'a>

pub fn into_bytes(self) -> &'a [u8]
