Struct SecretKey 

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

32 字节密钥材料，析构时自动擦除。

刻意不实现 Copy/Clone，避免密钥在栈上留下无法追踪的副本；确实需要复制时用 SecretKey::duplicate，让复制行为在代码中显式可见。

Implementations

impl SecretKey

pub const fn from_bytes(bytes: [u8; 32]) -> Self

由原始字节构造。

pub const fn as_bytes(&self) -> &[u8; 32]

借出底层字节。

pub fn duplicate(&self) -> Self

显式复制。命名刻意不叫 clone，以便审计时能搜出所有密钥复制点。

pub fn random() -> Self

生成随机密钥。

Trait Implementations

impl Debug for SecretKey

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

刻意不打印密钥内容，避免日志泄露。

impl Drop for SecretKey

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 Zeroize for SecretKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
