Implementations
impl<R: Read> ScannerAscii<R>
[src]
pub fn new(reader: R) -> ScannerAscii<R>
[src]
Create a scanner from a reader.
extern crate scanner_rust; use std::io; use scanner_rust::ScannerAscii; let mut sc = ScannerAscii::new(io::stdin());
impl ScannerAscii<File>
[src]
pub fn scan_path<P: AsRef<Path>>(
path: P
) -> Result<ScannerAscii<File>, ScannerError>
[src]
path: P
) -> Result<ScannerAscii<File>, ScannerError>
Create a scanner to read data from a file by its path.
extern crate scanner_rust; use scanner_rust::ScannerAscii; let mut sc = ScannerAscii::scan_path("Cargo.toml").unwrap();
impl<R: Read> ScannerAscii<R>
[src]
pub unsafe fn remove_heading_bytes_from_buffer(
&mut self,
number_of_bytes: usize
)
[src]
&mut self,
number_of_bytes: usize
)
Left shift (if necessary) the buffer to remove bytes from the start of the buffer. Typically, you should use this after peek
ing the buffer.
impl<R: Read> ScannerAscii<R>
[src]
pub fn next_char(&mut self) -> Result<Option<char>, ScannerError>
[src]
Read the next char. If the data is not a correct char, it will return a Ok(Some(REPLACEMENT_CHARACTER))
which is �. If there is nothing to read, it will return Ok(None)
.
extern crate scanner_rust; use scanner_rust::ScannerAscii; let mut sc = ScannerAscii::new("5 c ab".as_bytes()); assert_eq!(Some('5'), sc.next_char().unwrap()); assert_eq!(Some(' '), sc.next_char().unwrap()); assert_eq!(Some('c'), sc.next_char().unwrap()); assert_eq!(Some(' '), sc.next_char().unwrap()); assert_eq!(Some('a'), sc.next_char().unwrap()); assert_eq!(Some('b'), sc.next_char().unwrap()); assert_eq!(None, sc.next_char().unwrap());
pub fn next_line(&mut self) -> Result<Option<String>, ScannerError>

(\r\n
)). If there is nothing to read, it will return Ok(None)
.

pub fn drop_next_line(&mut self) -> Result<Option<usize>, ScannerError>
[src]
Drop the next line but not include the tailing line character (or line chracters like CrLf
(\r\n
)). If there is nothing to read, it will return Ok(None)
. If there are something to read, it will return Ok(Some(i))
. The i
is the length of the dropped line.

Read the next text until it reaches a specific boundary and parse it to a f64
value. If there is nothing to read, it will return Ok(None)
.
