Struct CustomEncoder 

pub struct CustomEncoder { /* private fields */ }

A custom encoder that wraps a callable.

This is useful for creating encoders from closures or function pointers without defining a new type. Closures may capture state.

Thread Safety

CustomEncoder is Send and Sync.

Example

use attackstr::{CustomEncoder, Encoder};

let salt = "abc".to_string();
let encoder = CustomEncoder::new(move |s: &str| format!("{salt}{s}"));
assert_eq!(encoder.encode("hello"), "abchello");

Implementations

impl CustomEncoder

pub fn new<F>(func: F) -> Self

where F: Fn(&str) -> String + Send + Sync + 'static,

Create a new CustomEncoder from a closure or function pointer.

Example:

use attackstr::{CustomEncoder, Encoder};

let encoder = CustomEncoder::new(|value| value.to_uppercase());
assert_eq!(encoder.encode("xss"), "XSS");

pub fn encode(&self, input: &str) -> String

Apply the encoding to an input string.

Example:

use attackstr::CustomEncoder;

let encoder = CustomEncoder::new(|value| format!("<{value}>"));
assert_eq!(encoder.encode("a"), "<a>");
