<a href="trait.BlockRngCore.html" title="trait rand_core::block::BlockRngCore"><code>BlockRngCore</code></a> with <code>u32</code> array buffer; i.e. this can be used to implement
|
|
a full RNG from just a <code>generate</code> function.</p>
|
|
<p>The <code>core</code> field may be accessed directly but the results buffer may not.
|
|
PRNG implementations can simply use a type alias
|
|
(<code>pub type MyRng = BlockRng<MyRngCore>;</code>) but might prefer to use a
|
|
wrapper type (<code>pub struct MyRng(BlockRng<MyRngCore>);</code>); the latter must
|
|
re-implement <code>RngCore</code> but hides the implementation details and allows
|
|
extra functionality to be defined on the RNG
|
|
(e.g. <code>impl MyRng { fn set_stream(...){...} }</code>).</p>
|
|
<p><code>BlockRng</code> has heavily optimized implementations of the <a href="../trait.RngCore.html" title="trait rand_core::RngCore"><code>RngCore</code></a> methods
|
|
reading values from the results buffer, as well as
|
|
calling <a href="trait.BlockRngCore.html#tymethod.generate" title="method rand_core::block::BlockRngCore::generate"><code>BlockRngCore::generate</code></a> directly on the output array when
|
|
<a href="../trait.RngCore.html#tymethod.fill_bytes" title="method rand_core::RngCore::fill_bytes"><code>fill_bytes</code></a> is called on a large array. These methods also handle
|
|
the bookkeeping of when to generate a new batch of values.</p>
|
|
<p>No whole generated <code>u32</code> values are thrown away and all values are consumed
|
|
in-order. <a href="../trait.RngCore.html#tymethod.next_u32" title="method rand_core::RngCore::next_u32"><code>next_u32</code></a> simply takes the next available <code>u32</code> value.
|
|
<a href="../trait.RngCore.html#tymethod.next_u64" title="method rand_core::RngCore::next_u64"><code>next_u64</code></a> is implemented by combining two <code>u32</code> values, least
|
|
significant first. <a href="../trait.RngCore.html#tymethod.fill_bytes" title="method rand_core::RngCore::fill_bytes"><code>fill_bytes</code></a> consume a whole number of <code>u32</code> values,
|
|
converting each <code>u32</code> to a byte slice in little-endian order. If the requested byte
|
|
length is not a multiple of 4, some bytes will be discarded.</p>
|
|
<p>See also <a href="struct.BlockRng64.html" title="struct rand_core::block::BlockRng64"><code>BlockRng64</code></a> which uses <code>u64</code> array buffers. Currently there is
|
|
no direct support for other buffer types.</p>
|
|
<p>For easy initialization <code>BlockRng</code> also implements <a href="../trait.SeedableRng.html" title="trait rand_core::SeedableRng"><code>SeedableRng</code></a>.</p>
