Struct combine::stream::buf_reader::BufReader[][src]

pub struct BufReader<R> { /* fields omitted */ }
Expand description

BufReader used by Decoder when it is constructed with Decoder::new_bufferless

Implementations

Creates a new BufReader with a default buffer capacity. The default is currently 8 KB, but may change in the future.

Creates a new BufReader with the specified buffer capacity.

Gets a reference to the underlying reader.

It is inadvisable to directly read from the underlying reader.

Gets a mutable reference to the underlying reader.

It is inadvisable to directly read from the underlying reader.

Consumes this BufWriter, returning the underlying reader.

Note that any leftover data in the internal buffer is lost.

Returns a reference to the internally buffered data.

Unlike fill_buf, this will not attempt to fill the buffer if it is empty.

Trait Implementations

Returns the contents of the internal buffer, filling it with more data from the inner reader if it is empty. Read more

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to read. Read more

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

recently added

Check if the underlying Read has any data left to be read. Read more

Read all bytes into buf until the delimiter byte or EOF is reached. Read more

Read all bytes until a newline (the 0xA byte) is reached, and append them to the provided buffer. Read more

Returns an iterator over the contents of this reader split on the byte byte. Read more

Returns an iterator over the lines of this reader. Read more

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

Read all bytes until EOF in this source, placing them into buf. Read more

Read all bytes until EOF in this source, appending them to buf. Read more

Read the exact number of bytes required to fill buf. Read more

Creates a “by reference” adaptor for this instance of Read. 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
