Struct layered_io::LayeredReader[][src]

pub struct LayeredReader<Inner> { /* fields omitted */ }
Expand description

Adapts an Read to implement ReadLayered.

Implementations

Construct a new LayeredReader which wraps inner with default settings.

Construct a new LayeredReader which wraps inner. When inner reports end of stream (by returning 0), report a push but keep the stream open and continue to read data on it.

For example, when reading a file, when the reader reaches the end of the file it will report it, but consumers may wish to continue reading in case additional data is appended to the file.

Construct a new LayeredReader which wraps an inner which reads its input line-by-line, such as stdin on a terminal.

Consume this LayeredReader and return the inner stream.

Extracts the raw file descriptor. Read more

Close the resource and abandon any pending buffered contents or errors.

A suggested size, in bytes, for buffering for performance.

Formats the value using the given formatter. Read more

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

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

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

Determines if this Reader has an efficient read_vectored implementation. Read more

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

Determines if this Reader can work with buffers of uninitialized memory. Read more

Transforms this Read instance to an Iterator over its bytes. Read more

Creates an adaptor which will chain this stream with another. Read more

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

Like Read::read, but also returns a Status.

Like Read::read_vectored, but also returns a Status.

Like Read::read_exact, but uses read_with_status to avoid performing an extra read at the end. Read more

Some streams require a buffer of at least a certain size.
