A "bit matrix" is basically a matrix of booleans represented as
one gigantic bitvector. In other words, it is as if you have
rows
bitvectors, each of length columns
.
Fields
columns: usize

Create a new rows x columns
matrix, initially empty.

The range of bits for a given row.

Sets the cell at (row, column)
to true. Put another way, add
column
to the bitset for row
.
Returns true if this changed the matrix, and false otherwise.

Do the bits from row
contain column
? Put another way, is
the matrix cell at (row, column)
true? Put yet another way,
if the matrix represents (transitive) reachability, can
row
reach column
?
pub fn intersection(&self, a: R, b: R) -> Vec<C>
[src]
pub fn intersection(&self, a: R, b: R) -> Vec<C>
🔬 This is a nightly-only experimental API. (rustc_private
)

Returns those indices that are true in rows a
and b
. This
is an O(n) operation where n
is the number of elements
(somewhat independent from the actual size of the
intersection, in particular).
pub fn merge(&mut self, read: R, write: R) -> bool
[src]
pub fn merge(&mut self, read: R, write: R) -> bool
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml

Add the bits from row read
to the bits from row write
,
return true if anything changed.
This is used when computing transitive reachability because if
you have an edge write -> read
, because in that case
write
can reach everything that read
can (and
potentially more).

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
