Struct InputStream 

pub struct InputStream<B> { /* private fields */ }

C++-like Stream.

This struct provides a way to read from a buffer that implements BufRead.

It implements BufReadExt for reading characters, strings, and lines.

Implementations

impl<B: BufRead> InputStream<B>

pub const fn new(buffer: B) -> Self

Create an input stream from a buffer that implements BufRead.

Trait Implementations

impl<B: BufRead> BufReadExt for InputStream<B>

fn get_cur_line(&self) -> &str

Get the current line whatever state it is.

unsafe fn skip(&mut self, n: usize)

Skip n bytes.

fn read_buf(&mut self) -> Result<bool, StreamError>

Try to fill the buffer with a new line, ignoring the current line.

fn fill_buf(&mut self) -> Result<(), StreamError>

Fill the buffer with a new line, ignoring the current line.

fn is_eol(&self) -> bool

Check whether is at the end of the line.

fn get_line(&mut self) -> Result<&str, StreamError>

Get the current line. Read a new line if current line is empty.

fn get_in_cur_line(&mut self) -> Result<Option<char>, StreamError>

Get the next character in current line, if any.

fn peek_in_cur_line(&mut self) -> Option<char>

Peek the next character in current line, if any.

fn fill_buf_if_eol(&mut self) -> Result<bool, StreamError>

Fill the buffer with a new line if the current line is empty.

fn try_get(&mut self) -> Result<char, StreamError>

Get a single character.

fn try_peek(&mut self) -> Result<char, StreamError>

Peek a single character. Read a new line if current line is empty.

fn try_skip_any(&mut self) -> Result<(), StreamError>

Skip a single character.

fn try_skip_eol(&mut self) -> Result<Option<bool>, StreamError>

Go to the next line if the remaining part are end of line characters.

fn try_get_line(&mut self) -> Result<&str, StreamError>

Get a single line. The trailing newline will be consumed and trimmed. but no other white spaces will be trimmed.

fn try_get_line_some(&mut self) -> Result<&str, StreamError>

Get a single not-empty line. The trailing newline will be consumed and trimmed.
