pub enum IndexVec {
    // some variants omitted
}
Expand description

A vector of indices.

Multiple internal representations are possible.

Implementations

Returns the number of indices

Returns true if the length is 0.

Return the value at the given index.

(Note: we cannot implement std::ops::Index because of lifetime restrictions.)

Return result as a Vec<usize>. Conversion may or may not be trivial.

Iterate over the indices as a sequence of usize values

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Converts to this type from the input type.
Converts to this type from the input type.

Convert into an iterator over the indices as a sequence of usize values

The type of the elements being iterated over.
Which kind of iterator are we turning this into?
This method tests for self and other values to be equal, and is used by ==. Read more
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
