Struct PrivateKey 

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

secp256k1 private key (32 bytes).

Not Copy — copies of secret material should be intentional.

Implementations

impl PrivateKey

pub const LENGTH: usize = PRIVATE_KEY_LENGTH

Length in bytes.

pub fn new(b: &[u8]) -> Result<Self, Error>

Construct from raw bytes.

pub fn from_hex(s: &str) -> Result<Self, Error>

Parse from hex (with or without 0x prefix).

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

Borrow the raw bytes.

pub fn to_hex(&self) -> String

Lowercase hex, no 0x prefix.

pub fn public_key(&self) -> Result<PublicKey, Error>

Derive the uncompressed (64-byte X || Y) public key.

pub fn sign(&self, data: &[u8]) -> Result<Signature, Error>

Sign data using the Ethereum signed-message scheme and return a 65-byte R || S || V signature with V ∈ {27, 28}.

Trait Implementations

impl Clone for PrivateKey

fn clone(&self) -> PrivateKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrivateKey

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

Formats the value using the given formatter.

impl FromStr for PrivateKey

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl PartialEq for PrivateKey

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
