}Expand description
A helper trait for converting a ZcashAddress into another type.
§Examples
use zcash_address::{ConversionError, Network, TryFromAddress, UnsupportedAddress, ZcashAddress};
#[derive(Debug)]
struct MySapling([u8; 43]);
// Implement the TryFromAddress trait, overriding whichever conversion methods match your
// requirements for the resulting type.
impl TryFromAddress for MySapling {
// In this example we aren't checking the validity of the inner Sapling address,
// but your code should do so!
type Error = &'static str;
fn try_from_sapling(
net: Network,
data: [u8; 43],
) -> Result<Self, ConversionError<Self::Error>> {
Ok(MySapling(data))
}
}
// For a supported address type, the conversion works.
let addr: ZcashAddress =
"zs1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqpq6d8g"
.parse()
.unwrap();
assert!(addr.convert::<MySapling>().is_ok());
// For an unsupported address type, we get an error.
let addr: ZcashAddress = "t1Hsc1LR8yKnbbe3twRp88p6vFfC5t7DLbs".parse().unwrap();
assert_eq!(
addr.convert::<MySapling>().unwrap_err().to_string(),
"Zcash transparent P2PKH addresses are not supported",
);Required Associated Types§
sourcetype Error
type Error
Conversion errors for the user type (e.g. failing to parse the data passed to
Self::try_from_sapling as a valid Sapling address).
