Enum SeedDecodeError 

pub enum SeedDecodeError {
    InvalidHex(FromHexError),
    WrongLength {
        expected: usize,
        got: usize,
    },
}

Errors from hex seed decoding.

Usage:

match decode_seed_hex("bad") {
    Err(SeedDecodeError::InvalidHex(_)) => { /* not valid hex */ }
    Err(SeedDecodeError::WrongLength { .. }) => { /* not 32 bytes */ }
    Ok(seed) => { /* use seed */ }
}

Variants

InvalidHex(FromHexError)

The input string is not valid hexadecimal.

WrongLength

The decoded bytes are not exactly 32 bytes.

Fields

expected: usize

Expected byte count (always 32).

got: usize

Actual byte count after decoding.

Trait Implementations

impl Debug for SeedDecodeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SeedDecodeError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SeedDecodeError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
