A type that represents when cargo treats two Versions as compatible.
Versions
a
and b
are compatible if their left-most nonzero digit is the
same.Type Definitions
Find the activated version of a crate based on the name, source, and semver compatibility.
By storing this in a hash map we ensure that there is only one
semver compatible version of each crate.
This all so stores the
ContextAge
.When backtracking it can be useful to know how far back to go.
The
ContextAge
of a Context
is a monotonically increasing counter of the number
of decisions made to get to this state.
Several structures store the ContextAge
when it was added,
to be used in find_candidate
for backtracking.
