[[bbv2.builtin.features.local-visibility]]`local-visibility`::
*Allowed values:* `global`, `protected`, `hidden`.
+
This feature has the same effect as the
<<bbv2.builtin.features.visibility,`visibility`>> feature but is intended
to be used by targets that require a particular symbol visibility. Unlike the
`visibility` feature, `local-visibility` is not inherited by the target
dependencies and only affects the target to which it is applied.
+
The `local-visibility` feature supports the same values with the same meaning
as the `visibility` feature. By default, if `local-visibility` is not specified
for a target, the value of the `visibility` feature is used.
