[−][src]Enum rcore::Writer
This union acts as thin abstraction layer over over input streams. Its goal is to allow allow seamingless redirection of output to either a buffer, a file or even terminal IO.
Methods
impl Writer
[src]
pub fn new_write(out: Box<dyn Write>) -> Self
[src]
pub fn new_buf() -> Self
[src]
Returns a new buffer based Writer.
pub fn bytes(self) -> Option<Vec<u8>>
[src]
This function consumes the Writer object, it returns the data stored there if the object is buffer based.
pub fn utf8_string(self) -> Option<String>
[src]
This function consumes the Writer object, it returns UTF-8 String representation of the data stored there if it is buffer. based and the buffer holds UTF-8 data.
pub fn bytes_ref(&self) -> Option<&Vec<u8>>
[src]
This function returns a reference to the data stored in respective Writer if the object is buffer based.
pub fn bytes_mut(&mut self) -> Option<&mut Vec<u8>>
[src]
This function returns a mutable reference to the data stored in respective Writer if the object is buffer. based.
