Struct StringReader

pub struct StringReader<R: StringRead = String> {
    pub queue: VecDeque<String>,
    pub reader: Option<R>,
}

An equivalent of std::io::BufReader but for String instead of char.

Fields

queue: VecDeque<String>

reader: Option<R>

Implementations

impl<R: StringRead> StringReader<R>

pub fn new() -> Self

Equivalent to default().

Trait Implementations

impl<R: StringRead> BufRead for StringReader<R>

fn fill_buf(&mut self) -> Result<&[u8]>

Returns the contents of the internal buffer, filling it with more data, via Read methods, if empty.

fn consume(&mut self, amt: usize)

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.

fn has_data_left(&mut self) -> Result<bool, Error>

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

Checks if there is any data left to be read.

fn read_until(&mut self, byte: u8, buf: &mut Vec<u8>) -> Result<usize, Error>

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

fn skip_until(&mut self, byte: u8) -> Result<usize, Error>

Skips all bytes until the delimiter byte or EOF is reached.

fn read_line(&mut self, buf: &mut String) -> Result<usize, Error>

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

fn split(self, byte: u8) -> Split<Self>

where Self: Sized,

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

fn lines(self) -> Lines<Self>

where Self: Sized,

Returns an iterator over the lines of this reader.

impl<R: Clone + StringRead> Clone for StringReader<R>

fn clone(&self) -> StringReader<R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<R: Debug + StringRead> Debug for StringReader<R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R: StringRead> Default for StringReader<R>

fn default() -> Self

Returns the “default value” for a type.

impl<R: StringRead> From<R> for StringReader<R>

fn from(value: R) -> Self

Converts to this type from the input type.

impl<R: StringRead> From<VecDeque<String>> for StringReader<R>

fn from(value: VecDeque<String>) -> Self

Converts to this type from the input type.

impl<R: StringRead> Read for StringReader<R>

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.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

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

fn is_read_vectored(&self) -> bool

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

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

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

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

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

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

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

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

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

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

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

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

impl<R: StringRead> StrRead for StringReader<R>

fn peek_str(&self) -> Option<&str>

fn is_empty(&self) -> bool

Check if there is nothing to pop.

impl<R: StringRead> StringRead for StringReader<R>

fn pop_string(&mut self) -> Option<String>

Remove the next String and return it.

fn peek_mut_string(&mut self) -> Option<&mut String>

Get a mutable reference to the next String.

fn map_string(&mut self, f: impl FnMut(&mut String))

impl<R: StringRead> StringWrite for StringReader<R>

fn push_string(&mut self, s: String)

Insert a String into the reader.

fn shift_string(&mut self, s: String)

Insert a String into the reader.
