Struct rustc_index::interval::SparseIntervalMatrix

pub struct SparseIntervalMatrix<R, C>where
    R: Idx,
    C: Idx,{
    rows: IndexVec<R, IntervalSet<C>>,
    column_size: usize,
}

This data structure optimizes for cases where the stored bits in each row are expected to be highly contiguous (long ranges of 1s or 0s), in contrast to BitMatrix and SparseBitMatrix which are optimized for “random”/non-contiguous bits and cheap(er) point queries at the expense of memory usage.

Fields

rows: IndexVec<R, IntervalSet<C>>

column_size: usize

Trait Implementations

impl<R, C> Clone for SparseIntervalMatrix<R, C>where
    R: Idx + Clone,

fn clone(&self) -> SparseIntervalMatrix<R, C>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
