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