}Expand description
A region to absorb presented data and present it as a type with a lifetime.
This type absorbs data and provides an index to look up an equivalent representation of this data at a later time. It is up to an implementation to select the appropriate presentation of the data, and what data it can absorb.
Implement the Push trait for all types that can be copied into a region.
Required Associated Types§
Required Methods§
sourcefn merge_regions<'a>(regions: impl Iterator<Item = &'a Self> + Clone) -> Selfwhere
Self: 'a,
fn merge_regions<'a>(regions: impl Iterator<Item = &'a Self> + Clone) -> Selfwhere
Self: 'a,
Construct a region that can absorb the contents of regions in the future.
sourcefn index(&self, index: Self::Index) -> Self::ReadItem<'_>
fn index(&self, index: Self::Index) -> Self::ReadItem<'_>
Index into the container. The index must be obtained by pushing data into the container.
sourcefn reserve_regions<'a, I>(&mut self, regions: I)
fn reserve_regions<'a, I>(&mut self, regions: I)
Ensure that the region can absorb the items of regions without reallocation
Object Safety§
This trait is not object safe.
