A secret key for ECDSA signature verification over the secp256k1 curve.
Implementations§
Source§impl SigningKey
impl SigningKey
Sourcepub fn new() -> SigningKey
pub fn new() -> SigningKey
Generates a new random signing key using the OS random number generator.
This is cryptographically secure as long as rand::rng remains so.
Sourcepub fn with_rng<R>(rng: &mut R) -> SigningKeywhere
R: CryptoRng,
pub fn with_rng<R>(rng: &mut R) -> SigningKeywhere
R: CryptoRng,
Generates a new signing key using the provided random number generator.
Sourcepub fn public_key(&self) -> PublicKey
pub fn public_key(&self) -> PublicKey
Gets the public key that corresponds to this signing key.
Sourcepub fn sign(&self, message: Word) -> Signature
pub fn sign(&self, message: Word) -> Signature
Signs a message (represented as a word) with this signing key.
Sourcepub fn sign_prehash(&self, message_digest: [u8; 32]) -> Signature
pub fn sign_prehash(&self, message_digest: [u8; 32]) -> Signature
Signs a pre-hashed message with this signing key.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.

This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
