Trait Parser 

Source 
pub trait Parser {
    // Required methods
    fn feed(&mut self, bytes: &[u8]) -> Option<usize>;
    fn eof_error(self, content: &[u8]) -> SyntaxError;
}
Expand description

Used to decouple reading of data from data source and parsing XML structure from it. This is a state preserved between getting chunks of bytes from the reader.

This trait is implemented for every parser that processes piece of XML grammar.

Required Methods§

Source

fn feed(&mut self, bytes: &[u8]) -> Option<usize>

Process new data and try to determine end of the parsed thing.

Returns position of the end of thing in bytes in case of successful search and None otherwise.

§Parameters
  • bytes: a slice to find the end of a thing. Should contain text in ASCII-compatible encoding
Source

fn eof_error(self, content: &[u8]) -> SyntaxError

Returns parse error produced by this parser in case of reaching end of input without finding the end of a parsed thing.

§Parameters
  • content: the content that was read before EOF. Some parsers may use this to provide more specific error messages.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
