5.1 Safe Homogenous Vectors🔗ℹ

 (require ffi/vector) package: base

Homogenous vectors are similar to C vectors (see Safe C Vectors), except that they define different types of vectors, each with a fixed element type. An exception is the u8 family of bindings, which are just aliases for byte-string bindings; for example, make-u8vector is an alias for make-bytes.
