Struct geo::MultiLineString [−][src]
pub struct MultiLineString<T>(pub Vec<LineString<T>, Global>)
where
T: CoordNum;
A collection of
LineString
s. Can
be created from a Vec
of LineString
s or from an
Iterator which yields LineString
s. Iterating over this
object yields the component LineString
s.
Semantics
The boundary of a MultiLineString
is obtained by
applying the “mod 2” union rule: A Point
is in the
boundary of a MultiLineString
if it is in the
boundaries of an odd number of elements of the
MultiLineString
.
The interior of a MultiLineString
is the union of
the interior, and boundary of the constituent
LineString
s, except for the boundary as defined
above. In other words, it is the set difference of the
boundary from the union of the interior and boundary of
the constituents.
A MultiLineString
is simple if and only if all of
its elements are simple and the only intersections
between any two elements occur at Point
s that are on
the boundaries of both elements. A MultiLineString
is
closed if all of its elements are closed. The boundary
of a closed MultiLineString
is always empty.
Implementations

[src]
T: CoordNum,
pub fn is_closed(&self) -> bool
[src]
True if the MultiLineString is empty or if all of its LineStrings are closed - see
