Hrp

Struct Hrp 

Source
pub struct Hrp(pub String);
Expand description

Human-readable part (HRP) of Bech32 structure.

A valid HRP string must meet all following conditions:

  • String length must be in the range 1..84.
  • Must only contain ASCII characters in the range 33..127.
  • Must not contain a mixture of uppercase and lowercase alphabetic characters.

Note: Stored as lowercase.

§Examples

Parse string as Hrp:

use pbech32::Hrp;

let s = "testhrp"; // hrp string
let hrp: Hrp = s.parse()?; // parse string

Convert Hrp to a string:

use pbech32::Hrp;

let s = "foobar"; // hrp string
let hrp: Hrp = s.parse()?; // parse string
assert_eq!(hrp.to_string(), "foobar"); // check result

Convert Hrp to a &str with Hrp::as_ref():

use pbech32::Hrp;

let s = "foobar"; // hrp string
let hrp: Hrp = s.parse()?; // parse string
assert_eq!(hrp.as_ref(), "foobar"); // check result

Strings which contain all uppercase characters are converted to lowercase when parsed as an Hrp:

use pbech32::Hrp;

let hrp: Hrp = "TESTHRP".parse()?; // parse hrp string
assert_eq!(hrp.to_string(), "testhrp"); // check result

Parsing will fail if the given string is not a valid human-readable part. For example, here is a mixed-case string:

use pbech32::{Err, Hrp};

let s = "FOObar"; // mixed-case string
let got = s.parse::<Hrp>(); // parse string
assert_eq!(got, Err(Err::MixedCase(3, 0))); // check result
