Trait Encoder

Source

pub trait Encoder {
    // Required method
    fn encode(&self, input: &str) -> String;
}

Expand description

A trait for encoding transforms.

Implement this trait to create custom encoders that can be used with the attackstr encoding system.

§Thread Safety

This trait does not require Send or Sync. Thread-safety depends on the concrete implementing type.

§Example

use attackstr::Encoder;

struct Rot13Encoder;

impl Encoder for Rot13Encoder {
    fn encode(&self, input: &str) -> String {
        input.chars().map(|c| match c {
            'a'..='m' | 'A'..='M' => (c as u8 + 13) as char,
            'n'..='z' | 'N'..='Z' => (c as u8 - 13) as char,
            _ => c,
        }).collect()
    }
}

let encoder = Rot13Encoder;
assert_eq!(encoder.encode("hello"), "uryyb");
