Trait Preprocessor 

pub trait Preprocessor: Send + Sync {
    // Required methods
    fn process(&mut self, data: &[u8]) -> (Vec<u8>, Vec<ParseError>);
    fn fork(&self) -> Box<dyn Preprocessor>;
    fn splitter(&self) -> Option<Box<dyn Splitter>>;
}

Trait for preprocessing raw data before parsing.

Required Methods

fn process(&mut self, data: &[u8]) -> (Vec<u8>, Vec<ParseError>)

Process raw input data and return transformed data.

Arguments

• data - Raw input data bytes

Returns

A PreprocessResult containing the transformed data or errors.

fn fork(&self) -> Box<dyn Preprocessor>

Create a new preprocessor with the same configuration as self.

Used by multithreaded transport endpoints to create multiple parallel input pipelines.

fn splitter(&self) -> Option<Box<dyn Splitter>>

Returns an object that can be used to break a stream of incoming data into complete records to pass to Preprocessor::process. If the object is None, the parser’s splitter object will actually be used.
