Struct In 

pub struct In<B: BufRead> { /* private fields */ }

General Input (stdin, file, socket, etc.).

Implementations

impl<B: BufRead> In<B>

pub fn new(bufread: B) -> Self

Creates a new instance of BaseInput.

pub fn is_empty(&mut self) -> bool

Returns true if the input stream has more data, returns false otherwise.

pub fn read_int<T>(&mut self) -> Result<T>

where T: PrimInt + FromStr,

Reads an integer from the input stream.

The integer type is one of i8, i16, i32, i64, i128, isize, u8, u16, u32, u64, u128, or usize.

Errors

Same as Scanner::next_int.

pub fn read_float<T>(&mut self) -> Result<T>

where T: PrimFloat + FromStr,

Reads a floating point number from the input stream.

The integer type is one of f32 or f64.

Errors

Same as Scanner::next_float.

pub fn read_all_ints<T>(&mut self) -> Result<Vec<T>>

where T: PrimInt + FromStr,

Reads all integers from the input stream using the internal scanner, consuming all the content in the input stream, reading the content in a token-by-token streaming mode.

Errors

Same as Scanner::next_int.

pub fn read_string(&mut self) -> Result<String>

Read a string token from the input stream.

Errors

Same as Scanner::next_token.

pub fn read_all_strings(&mut self) -> Result<Vec<String>>

Reads all string tokens from the input stream using the internal scanner, consuming all the content in the input stream, reading the content in a token-by-token streaming mode.

Errors

Same as Scanner::next_token.
