R: Cast a list to vector of specific type

vec_list_cast {vctrs} | R Documentation

## Cast a list to vector of specific type

### Description

This is a function for developers to use when extending vctrs. It casts a list to a more specific vectoring type, keeping the length constant. It does this by discarding (with a warning), any elements after the 1. It is called from `vec_cast.XYZ.list()` methods to preserve symmetry with `vec_cast.list.XYZ()`.

### Usage

    vec_list_cast(x, to, ..., x_arg = "", to_arg = "")

### Arguments

`x` | A list
`to` | Type to coerce to
`...` | These dots are for future extensions and must be empty.

### Details

See `vignette("s3-vector")` for details.
