A trait for providing crate::seed::RngSeed with common initialization strategies. This trait is not object safe and is also a sealed trait.

Required Methods

fn from_seed(seed: R::Seed) -> Self

Initialize a SeedSource from a given seed value.

fn get_seed(&self) -> &R::Seed

Returns a reference of the seed value.

fn clone_seed(&self) -> R::Seed

Returns a cloned instance of the seed value.

Provided Methods

fn from_entropy() -> Self

where Self: Sized,

👎Deprecated: use either SeedSource::from_local_entropy or SeedSource::from_os_rng instead

Initialize a SeedSource from a seed value obtained from a user-space RNG source.

Panics

This method panics if for whatever reason it is unable to source entropy from the User-Space/OS/Hardware source.

fn try_from_local_entropy() -> Result<Self, AccessError>

where Self: Sized,

Available on crate feature thread_local_entropy only.

Initialize a SeedSource from a seed value obtained from a user-space RNG source. This is usually much, much faster than sourcing entropy from OS/Hardware sources.

fn from_local_entropy() -> Self

where Self: Sized,

Available on crate feature thread_local_entropy only.

Initialize a SeedSource from a seed value obtained from a user-space RNG source. This is usually much, much faster than sourcing entropy from OS/Hardware sources.

Panics

This method panics if for whatever reason it is unable to source entropy from the User-Space source.

fn try_from_os_rng() -> Result<Self, OsError>

where Self: Sized,

Initialize a SeedSource from a seed value obtained from an OS/Hardware RNG source.

fn from_os_rng() -> Self

where Self: Sized,

Initialize a SeedSource from a seed value obtained from an OS/Hardware RNG source.

Panics

This method panics if for whatever reason it is unable to source entropy from an OS/Hardware source.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
