pub struct Sm2Service;Expand description
SM2 静态门面（对应 PHP 版 Sm2EncryptionService）。
Implementations§
Source§impl Sm2Service
impl Sm2Service
Sourcepub fn encrypt(plaintext: &[u8], public_key_hex: &str) -> Result<String>
pub fn encrypt(plaintext: &[u8], public_key_hex: &str) -> Result<String>
公钥加密，返回十六进制密文（C1C3C2）。
Sourcepub fn generate_key_pair_hex() -> Result<KeyPairHex>
pub fn generate_key_pair_hex() -> Result<KeyPairHex>
生成密钥对：私钥用系统 CSPRNG 采样（不经任何非密码学随机源）。
Sourcepub fn sign(message: &[u8], private_key_hex: &str) -> Result<String>
pub fn sign(message: &[u8], private_key_hex: &str) -> Result<String>
私钥签名，返回定长 64 字节 r‖s 的十六进制（128 位）。
用户标识固定为 DEFAULT_DIST_ID；随机数 k 走 RFC 6979 确定性
派生（同一私钥 + 同一消息必得同一签名，不依赖运行时随机源）。
私钥格式非法（十六进制或长度）返回 Error::InvalidKey，
其余签名失败返回 Error::SignFailed。
Sourcepub fn verify(
message: &[u8],
signature_hex: &str,
public_key_hex: &str,
) -> Result<()>
pub fn verify( message: &[u8], signature_hex: &str, public_key_hex: &str, ) -> Result<()>
公钥验签。签名不对、消息被改、公钥 / 签名格式错误一律
Error::VerificationFailed（与契约一致，不区分原因）。
公钥写法接受与非对称加密相同的三种形式；用户标识固定为
DEFAULT_DIST_ID，签名方 ID 不一致时验签必然失败。

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.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
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
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
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().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
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;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
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);
