Struct FileBuf 

pub struct FileBuf { /* private fields */ }

Like [File] but owns the buffer.

Returned by load_file_buf. Requires a global allocator. For a file of statically-known size, you might want to use load_file instead.

Implementations

impl FileBuf

pub unsafe fn from_bytes(b: Box<[u8]>) -> Self

Construct FileBuf from raw bytes.

The main purpose of this function is to support convering FileBuf 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) -> FontBuf

pub fn into_image(self) -> ImageBuf

pub fn into_bytes(self) -> Box<[u8]>
