) -> bool
Expand description
Checks whether the given Expr
is a range equivalent to a RangeFull
.
For the lower bound, this means that:
- either there is none
- or it is the smallest value that can be represented by the range’s integer type For the upper bound, this means that:
- either there is none
- or it is the largest value that can be represented by the range’s integer type and is inclusive
- or it is a call to some container’s
len
method and is exclusive, and the range is passed to a method call on that same container (e.g.v.drain(..v.len())
) If the givenExpr
is not some kind of range, the function returnsfalse
.
