These functions return the non-coordinate information of a geometry and/or vector. They do not parse an entire geometry/vector and are intended to be very fast even for large vectors.

```
wk_meta(handleable, ...)
# S3 method for default
wk_meta(handleable, ...)
wk_vector_meta(handleable, ...)
# S3 method for default
wk_vector_meta(handleable, ...)
wk_meta_handler()

wk_geometry_type_label(geometry_type)
wk_geometry_type(geometry_type_label)
```

- handleable
A geometry vector (e.g.,

`wkb()`

,`wkt()`

,`xy()`

,`rct()`

, or`sf::st_sfc()`

) for which`wk_handle()`

is defined.- ...
Passed to the

`wk_handle()`

method.- geometry_type
An integer code for the geometry type. These integers follow the WKB specification (e.g., 1 for point, 7 for geometrycollection).

- geometry_type_label
A character vector of (lowercase) geometry type labels as would be found in WKT (e.g., point, geometrycollection).

A data.frame with columns:

`geometry_type`

: An integer identifying the geometry type. A value of 0 indicates that the types of geometry in the vector are not known without parsing the entire vector.`size`

: For points and linestrings, the number of coordinates; for polygons, the number of rings; for collections, the number of child geometries. A value of zero indicates an EMPTY geometry. A value of`NA`

means this value is unknown without parsing the entire geometry.`has_z`

:`TRUE`

if coordinates contain a Z value. A value of`NA`

means this value is unknown without parsing the entire vector.`has_m`

:`TRUE`

if coordinates contain an M value. A value of`NA`

means this value is unknown without parsing the entire vector.`srid`

: An integer identifying a CRS or NA if this value was not provided.`precision`

: A grid size or 0.0 if a grid size was not provided. Note that coordinate values may not have been rounded; the grid size only refers to the level of detail with which they should be interpreted.`is_empty`

:`TRUE`

if there is at least one non-empty coordinate. For the purposes of this value, a non-empty coordinate is one that contains at least one value that is not`NA`

or`NaN`

.
