Struct ExtendedKey 

pub struct ExtendedKey {
    pub prefix: Prefix,
    pub attrs: ExtendedKeyAttrs,
    pub key_bytes: [u8; 33],
}

Serialized extended key (e.g. xprv and xpub).

Fields

prefix: Prefix

Prefix (a.k.a. “version”) of the key (e.g. xprv, xpub)

attrs: ExtendedKeyAttrs

Extended key attributes.

key_bytes: [u8; 33]

Key material (may be public or private).

Includes an extra byte for a public key’s SEC1 tag.

Implementations

impl ExtendedKey

pub const BYTE_SIZE: usize = 78

Size of an extended key when deserialized into bytes from Base58.

pub const MAX_BASE58_SIZE: usize = 112

Maximum size of a Base58Check-encoded extended key in bytes.

Note that extended keys can also be 111-bytes.

pub fn write_base58<'a>(&self, buffer: &'a mut [u8; 112]) -> Result<&'a str>

Write a Base58-encoded key to the provided buffer, returning a &str containing the serialized data.

Note that this type also impls Display and therefore you can obtain an owned string by calling to_string().

Trait Implementations

impl Clone for ExtendedKey

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for ExtendedKey

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

Formats the value using the given formatter.

impl Drop for ExtendedKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl FromStr for ExtendedKey

type Err = Error

The associated error which can be returned from parsing.

fn from_str(base58: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl<K> TryFrom<ExtendedKey> for ExtendedPrivateKey<K>

where K: PrivateKey,

type Error = Error

The type returned in the event of a conversion error.

fn try_from(extended_key: ExtendedKey) -> Result<ExtendedPrivateKey<K>>

Performs the conversion.

impl<K> TryFrom<ExtendedKey> for ExtendedPublicKey<K>

where K: PublicKey,

type Error = Error

The type returned in the event of a conversion error.

fn try_from(extended_key: ExtendedKey) -> Result<ExtendedPublicKey<K>>

Performs the conversion.
