[−][src]Trait pct_str::Encoder

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

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

Required methods

`fn encode(&self, c: char) -> bool`

Decide if the given character must be encoded.

Note that the character % is always encoded even if this method returns false on it. Only characters with codepoint below 0x100 are encoded.
