Struct cfb::Stream [−][src]
pub struct Stream<'a, F: 'a> { /* fields omitted */ }
Expand description
A stream entry in a compound file, much like a filesystem file.
Implementations
Truncates or extends the stream, updating the size of this stream to
become size
.
If size
is less than the stream’s current size, then the stream will
be shrunk. If it is greater than the stream’s current size, then the
stream will be padded with zero bytes.
Does not change the current read/write position within the stream, unless the stream is truncated to before the current position, in which case the position becomes the new end of the stream.
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
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
can_vector
)Determines if this Read
er has an efficient read_vectored
implementation. Read more
read_initializer
)Determines if this Read
er 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” adapter for this instance of Read
. Read more
Creates an adapter which will chain this stream with another. Read more
Write a buffer into this writer, returning how many bytes were written. Read more
Flush this output stream, ensuring that all intermediately buffered contents reach their destination. Read more
can_vector
)Determines if this Write
r has an efficient write_vectored
implementation. Read more
Attempts to write an entire buffer into this writer. Read more
write_all_vectored
)Attempts to write multiple buffers into this writer. Read more
Writes a formatted string into this writer, returning any error encountered. Read more
