Struct eos_rs::api::io::file::FileReader

pub struct FileReader<'a>(_);

A reader for a File.

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

Implementations

impl<'a> FileReader<'a>

pub fn new(file: &'a mut File) -> Self

Trait Implementations

impl<'a> Drop for FileReader<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> Read for FileReader<'a>

fn read(&mut self, dst: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Selfwhere Self: Sized,

Creates a “by reference” adapter for this instance of Read.

fn bytes(self) -> Bytes<Self>where Self: Sized,

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

impl<'a> Seek for FileReader<'a>

fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seeking from End might not be properly implemented in the game.

Additionally the position must fit into an i32.

fn rewind(&mut self) -> Result<(), Error>

Rewind to the beginning of a stream.

fn stream_len(&mut self) -> Result<u64, Error>

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

Returns the current seek position from the start of the stream.
