impl PctString
sourcepub fn new<S: AsRef<str> + ?Sized>(str: &S) -> Result<PctString>
pub fn new<S: AsRef<str> + ?Sized>(str: &S) -> Result<PctString>
Create a new owned percent-encoded string.
The input slice is checked for correct percent-encoding and copied.
If the test fails, a InvalidEncoding
error is returned.

sourcepub fn encode<I: Iterator<Item = char>, E: Encoder>(
src: I,
encoder: E
) -> PctString
pub fn encode<I: Iterator<Item = char>, E: Encoder>(
src: I,
encoder: E
) -> PctString
Encode a string into a percent-encoded string.
This function takes an Encoder
instance to decide which character of the string must
be encoded.
Note that the character %
will always be encoded regardless of the provided Encoder
.
Example
use pct_str::{PctString, URIReserved};
let pct_string = PctString::encode("Hello World!".chars(), URIReserved);
println!("{}", pct_string.as_str()); // => Hello World%21

Methods from Deref<Target = PctStr>§
sourcepub fn len(&self) -> usize
