Struct ThreadEntropyRegistry 

pub struct ThreadEntropyRegistry { /* private fields */ }

Thread-local entropy source registry

This structure manages custom entropy sources for the current thread. It uses atomic operations to ensure thread safety.

Implementations

impl ThreadEntropyRegistry

pub const fn new() -> Self

Create a new thread entropy registry

pub unsafe fn register(&self, source: *const CustomEntropySource)

Register a custom entropy source for this thread

Arguments

• source - The custom entropy source to register

Safety

The source must remain valid for the lifetime of the registry. The caller is responsible for ensuring the source is not dropped while registered.

pub fn unregister(&self)

Unregister the current entropy source

pub unsafe fn get_source(&self) -> Option<&CustomEntropySource>

Get the currently registered entropy source

Returns

Returns a reference to the registered entropy source, or None if no source is registered.

Safety

The returned reference is only valid as long as the source remains registered and not dropped.

pub fn generate_entropy(&self, dest: &mut [u8]) -> Result<()>

Generate entropy using the registered source

Arguments

• dest - Buffer to fill with random bytes

Errors

Returns an error if no source is registered or if entropy generation fails.

Trait Implementations

impl Default for ThreadEntropyRegistry

fn default() -> Self

Returns the “default value” for a type.
