Struct Repeat 

#[non_exhaustive]
pub struct Repeat {
    #[doc(hidden)]
    pub byte: u8,
}

A reader which yields one byte over and over and over and over and over and…

This struct is generally created by calling repeat(). Please see the documentation of repeat() for more details.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

#[doc(hidden)]

byte: u8

Trait Implementations

impl Debug for Repeat

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

Formats the value using the given formatter.

impl Read for Repeat

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

This function is not supported by io::Repeat, because there’s no end of its data

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

This function is not supported by io::Repeat, because there’s no end of its data

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

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

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

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<()>

🔬This is a nightly-only experimental API. (read_buf #78485)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, buf: BorrowedCursor<'_>) -> Result<()>

🔬This is a nightly-only experimental API. (read_buf #78485)

Reads the exact number of bytes required to fill cursor.

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

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

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector #69941)

Determines if this Reader has an efficient read_vectored implementation.

fn by_ref(&mut self) -> &mut Self

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

where 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.

fn read_array<const N: usize>(&mut self) -> Result<[u8; N]>

where Self: Sized,

🔬This is a nightly-only experimental API. (read_array #148848)

Read and return a fixed array of bytes from this source.

impl SizeHint for Repeat

fn lower_bound(&self) -> usize

fn upper_bound(&self) -> Option<usize>

fn size_hint(&self) -> (usize, Option<usize>)
