pub struct ShardsRefMut<'a> { /* private fields */ }Expand description
Mutable reference to a shard array.
Implementations§
Source§impl<'a> ShardsRefMut<'a>
impl<'a> ShardsRefMut<'a>
Sourcepub fn dist2_mut(
&mut self,
pos: usize,
dist: usize,
) -> (&mut [[u8; 64]], &mut [[u8; 64]])
pub fn dist2_mut( &mut self, pos: usize, dist: usize, ) -> (&mut [[u8; 64]], &mut [[u8; 64]])
Returns mutable references to shards at pos and pos + dist.
See source code of Naive::fft for an example.
§Panics
If dist is 0 or either shard index is out of bounds.
Sourcepub fn dist4_mut(
&mut self,
pos: usize,
dist: usize,
) -> (&'_ mut [[u8; 64]], &'_ mut [[u8; 64]], &'_ mut [[u8; 64]], &'_ mut [[u8; 64]])
pub fn dist4_mut( &mut self, pos: usize, dist: usize, ) -> (&'_ mut [[u8; 64]], &'_ mut [[u8; 64]], &'_ mut [[u8; 64]], &'_ mut [[u8; 64]])
Returns mutable references to shards at
pos, pos + dist, pos + dist * 2 and pos + dist * 3.
See source code of Scalar::fft for an example
(specifically the private method fft_butterfly_two_layers).
§Panics
If dist is 0 or any shard index is out of bounds.
Sourcepub fn new(
shard_count: usize,
shard_chunk_count: usize,
data: &'a mut [[u8; 64]],
) -> Self
pub fn new( shard_count: usize, shard_chunk_count: usize, data: &'a mut [[u8; 64]], ) -> Self
Creates new ShardsRefMut that references given data.
Each shard contains shard_chunk_count chunks. Zero-length shards are supported.
§Panics
If shard_count * shard_chunk_count overflows or exceeds data.len().
Sourcepub fn split_at_mut(
&mut self,
mid: usize,
) -> (ShardsRefMut<'_>, ShardsRefMut<'_>)
pub fn split_at_mut( &mut self, mid: usize, ) -> (ShardsRefMut<'_>, ShardsRefMut<'_>)
Splits this ShardsRefMut into two so that
first includes shards 0..mid and second includes shards mid...
§Panics
If mid > self.len().
Sourcepub fn zero<R: RangeBounds<usize>>(&mut self, range: R)
pub fn zero<R: RangeBounds<usize>>(&mut self, range: R)
Fills the shards in range with zero bytes.
§Panics
If the range is reversed or extends beyond self.len().
