source§

impl<C: Codec, R> Region for CodecRegion<C, R>
where for<'a> R: Region<ReadItem<'a> = &'a [u8]> + 'a,

source§

fn merge_regions<'a>(regions: impl Iterator<Item = &'a Self> + Clone) -> Self
where Self: 'a,

Construct a region that can absorb the contents of regions in the future.

§

type Owned = Vec<u8>

An owned type that can be constructed from a read item.
§

type ReadItem<'a> = &'a [u8] where Self: 'a

The type of the data that one gets out of the container.
§

type Index = <R as Region>::Index

The type to index into the container. Should be treated as an opaque type, even if known.
source§

fn index(&self, index: Self::Index) -> Self::ReadItem<'_>

source§

fn reserve_regions<'a, I>(&mut self, regions: I)
where Self: 'a, I: Iterator<Item = &'a Self> + Clone,

source§

fn heap_size<F: FnMut(usize, usize)>(&self, callback: F)

Heap size, size - capacity
source§

fn reborrow<'b, 'a: 'b>(item: Self::ReadItem<'a>) -> Self::ReadItem<'b>
where C: 'a,
