Struct SaplingExtendedSpendingKey

pub struct SaplingExtendedSpendingKey(/* private fields */);

A Sapling Extended Spending Key, encoded as specified in ZIP 32

Implementations

impl SaplingExtendedSpendingKey

pub fn new(data: [u8; 169]) -> Self

Creates a new instance from a fixed-size byte array.

This is the primary constructor when you have an exact-sized array available.

pub fn len(&self) -> usize

Returns the length of this blob in bytes.

This will always return $size for this type.

pub fn is_empty(&self) -> bool

Returns true if this blob contains no bytes.

This will always return false for this type (unless $size is 0).

pub fn to_vec(&self) -> Vec<u8>

Converts this blob to a Vec<u8>, creating a copy of the data.

pub fn as_slice(&self) -> &[u8]

Exposes the underlying byte array as a slice.

pub fn as_bytes(&self) -> &[u8; 169]

Exposes the underlying byte array.

pub fn from_slice(data: &[u8]) -> Result<Self, TryFromSliceError>

Creates an instance from a slice of bytes.

Errors

Returns an error if the slice’s length doesn’t match the expected size ($size).

pub fn from_vec(data: Vec<u8>) -> Result<Self, TryFromSliceError>

Creates an instance from a Vec<u8>.

Errors

Returns an error if the vector’s length doesn’t match the expected size ($size).

pub fn from_hex(hex: &str) -> Result<Self, HexParseError>

Parses an instance from a hex string.

pub fn from_reversed_hex(hex: &str) -> Result<Self, HexParseError>

Parses an instance from a hex string in reversed byte order, such as is used for transaction identifiers and block hashes.

pub fn to_hex(&self) -> String

Formats the bytes of this object as a hex string.

impl PartialEq for SaplingExtendedSpendingKey

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
