Struct cat_reader::CatReader

pub struct CatReader<I: IntoIterator> where
    <I as IntoIterator>::Item: AsRef<Path>,  { /* fields omitted */ }

Simple adaptor for reading and chaining multiple files.

Methods

impl<I: IntoIterator> CatReader<I> where
    <I as IntoIterator>::Item: AsRef<Path>, 

fn new(iter: I) -> CatReader<I>

Creates a new CatReader from an iterator of file names.

fn buffered(iter: I) -> BufReader<CatReader<I>>

Convenient way to create a BufReader for a CatReader.

Trait Implementations

impl<I: IntoIterator> Read for CatReader<I> where
    <I as IntoIterator>::Item: AsRef<Path>, 

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_to_end(&mut self, buf: &mut Vec<u8>) -> 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, placing them into 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 Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chars(self) -> Chars<Self>

🔬 This is a nightly-only experimental API. (io)

the semantics of a partial read/write of where errors happen is currently unclear and may change

Transforms this Read instance to an Iterator over chars.

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

Creates an adaptor which will chain this stream with another.

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

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

impl<I: IntoIterator> Debug for CatReader<I> where
    <I as IntoIterator>::Item: AsRef<Path> + Debug,
    <I as IntoIterator>::IntoIter: Clone, 

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

Formats the value using the given formatter.
