\title{Does an environment have or see bindings?}
\usage{
env_has(env = caller_env(), nms, inherit = FALSE)
}
\arguments{
\item{env}{An environment.}

\item{nms}{A character vector of binding names for which to check
existence.}

\item{inherit}{Whether to look for bindings in the parent
environments.}
}
\value{
A named logical vector as long as \code{nms}.
}
\description{
\code{env_has()} is a vectorised predicate that queries whether an
environment owns bindings personally (with \code{inherit} set to
\code{FALSE}, the default), or sees them in its own environment or in
any of its parents (with \code{inherit = TRUE}).
}
\examples{
parent <- child_env(NULL, foo = "foo")
env <- child_env(parent, bar = "bar")

# env does not own `foo` but sees it in its parent environment:
env_has(env, "foo")
env_has(env, "foo", inherit = TRUE)
}
