Implementations§

impl Intent

source

pub fn to_encoded_string(&self) -> Result<String, IntentIdentifierError>

Encode Intent as a Diem intent identifier (https://dip.diem.com/dip-5/).

Example
use offchain::identifier::Intent;
use std::str::FromStr;
let identifier = "diem://dm1p7ujcndcl7nudzwt8fglhx6wxn08kgs5tm6mz4us2vfufk?c=XUS&am=4500";
let intent = Intent::from_str(identifier).unwrap();
assert_eq!(intent.to_encoded_string().unwrap(), identifier);

pub fn subaddress(&self) -> &Subaddress

source

pub fn currency(&self) -> Option<Currency>

source

pub fn amount(&self) -> Option<u64>
