#[non_exhaustive]
pub struct Empty;
Expand description
Empty ignores any data written via Write, and will always be empty
(returning zero bytes) when read via Read.
This struct is generally created by calling empty(). Please
see the documentation of empty() for more details.
Returns the contents of the internal buffer, filling it with more data, via Read methods, if empty. Read more
Marks the given amount of additional bytes from the internal buffer as having been read.
Subsequent calls to read only return bytes that have not been marked as read. Read more
🔬This is a nightly-only experimental API. (buf_read_has_data_left #86423)
Checks if there is any data left to be read. Read more
Reads all bytes into buf until the delimiter byte or EOF is reached. Read more
Skips all bytes until the delimiter byte or EOF is reached. Read more
Reads all bytes until a newline (the 0xA byte) is reached, and append
them to the provided String 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
Pull some bytes from this source into the specified buffer, returning
how many bytes were read. Read more
🔬This is a nightly-only experimental API. (read_buf #78485)
Pull some bytes from this source into the specified buffer. Read more
Like read, except that it reads into a slice of buffers. Read more
🔬This is a nightly-only experimental API. (can_vector #69941)
Determines if this Reader has an efficient read_vectored
implementation. Read more
Reads the exact number of bytes required to fill buf. Read more
🔬This is a nightly-only experimental API. (read_buf #78485)
Reads the exact number of bytes required to fill cursor. Read more
Reads all bytes until EOF in this source, placing them into buf. Read more
Reads all bytes until EOF in this source, appending them to buf. Read more
Creates a “by reference” adapter for this instance of Read. Read more
Transforms this Read instance to an Iterator over its bytes. Read more
Creates an adapter which will chain this stream with another. Read more
Creates an adapter which will read at most limit bytes from it. Read more
🔬This is a nightly-only experimental API. (read_array #148848)
Read and return a fixed array of bytes from this source. Read more
Writes a buffer into this writer, returning how many bytes were written. Read more
Like write, except that it writes from a slice of buffers. Read more
🔬This is a nightly-only experimental API. (can_vector #69941)
Attempts to write an entire buffer into this writer. Read more
🔬This is a nightly-only experimental API. (write_all_vectored #70436)
Attempts to write multiple buffers into this writer. Read more
Writes a formatted string into this writer, returning any error
encountered. Read more
Flushes this output stream, ensuring that all intermediately buffered
contents reach their destination. Read more
