Trait Encoder

Source

pub trait Encoder {
    // Required method
    fn encode(&self, c: char) -> bool;
}

Expand description

Encoding predicate.

Instances of this trait are used along with the encode function to decide which character must be percent-encoded.

This crate provides a simple implementation of the trait, UriReserved encoding characters reserved in the URI syntax.

§Example

use pct_str::{PctString, UriReserved};

let pct_string = PctString::encode("Hello World!".chars(), UriReserved::Any);
println!("{}", pct_string.as_str()); // => Hello World%21

Custom encoder implementation:

use pct_str::{PctString, UriReserved};

struct CustomEncoder;

impl pct_str::Encoder for CustomEncoder {
  fn encode(&self, c: char) -> bool {
    UriReserved::Any.encode(c) || c.is_uppercase()
  }
}

let pct_string = PctString::encode("Hello World!".chars(), CustomEncoder);
println!("{}", pct_string.as_str()); // => %48ello %57orld%21
