Struct fileinput::FileInput
[−]
[src]
pub struct FileInput { /* fields omitted */ }
A wrapper which reads from multiple streams.
Methods
impl FileInput
[src]
fn new<T>(paths: &[T]) -> Self where
T: Borrow<str>,
T: Borrow<str>,
Constructs a new FileInput
that will read from the files specified.
fn source(&self) -> Option<Source>
Returns the current source being read from.
This function will return None
if no reading has been done yet or all the inputs have
been drained.

impl Read for FileInput
[src]
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. Read more
fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>
1.0.0
Read all bytes until EOF in this source, placing them into buf
. Read more
fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>
1.0.0
Read all bytes until EOF in this source, placing them into buf
. Read more
fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>
1.6.0
Read the exact number of bytes required to fill buf
. Read more
fn by_ref(&mut self) -> &mut Self
1.0.0
Creates a "by reference" adaptor for this instance of Read
. Read more
fn bytes(self) -> Bytes<Self>
1.0.0
Transforms this Read
instance to an Iterator
over its bytes. Read more
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 char
s. Read more
fn chain<R>(self, next: R) -> Chain<Self, R> where
R: Read,
1.0.0
R: Read,
Creates an adaptor which will chain this stream with another. Read more
fn take(self, limit: u64) -> Take<Self>
1.0.0
Creates an adaptor which will read at most limit
bytes from it. Read more
