WKT is a general markup format in ASCII. It is described in detail on Wikipedia

Boost Geometry supports the common formats (POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON).

Because Boost.Geometry also supports Box and Segment geometries, which are not standard OGC geometries, there are some extensions:

Box

can be read from WKT by specifying either a polygon (with 4 points) or a specific BOX string (non OGC)
streamed to WKT as a POLYGON

Segment

can be read from WKT by specifying either a linestring (with 2 points) or a specific SEGMENT string (non OGC)
streamed to WKT as a LINESTRING

Ring

can be read from WKT by specifying a polygon (with no holes)
streamed to WKT as POLYGON
