Struct eos_rs::api::io::file::File

pub struct File(_);

A file in the NDS file-system.

Implementations

impl File

pub unsafe fn open<C: AsRef<CStr>>(path: C) -> Self

Opens a file from the ROM file system at the given path, sort of like C’s fopen(3) library function.

Safety

The file path must be a valid path to an existing file in the ROM file system.

You must make sure the file object or readers made for it are never accessed from code during interrupts.

pub fn reader(&mut self) -> FileReader<'_>

Returns a reader for the file (implements Read and Seek for it).

During the lifetime of the reader the NDS will be put in file-transfer mode, if it isn’t already.

pub fn len(&self) -> u32

Gets the size of the open file.

pub fn is_empty(&self) -> bool

Checks if the file has size 0.

Trait Implementations

impl Drop for File

fn drop(&mut self)

Executes the destructor for this type.
