Struct File 

pub struct File(/* private fields */);

File structure.

This structure is used to represent a file in the virtual file system. This is a wrapper around the virtual file system file identifier.

Trait Implementations

impl Debug for File

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl ErrorType for File

type Error = Error

Error type of all the IO operations on this type.

impl Write for File

async fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

async fn flush(&mut self) -> Result<(), Self::Error>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Write an entire buffer into this writer.

impl Write for File

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
