@item Cross Field and Cross Struct validations by using validation tags or
custom validators
@item Slice, Array and Map diving, which allows any or all levels of a
multidimensional field to be validated
@item Ability to dive into both map keys and values for validation
@item Handles type interface by determining it's underlying type prior to validation
@item Handles custom field types such as sql driver
@uref{https://golang.org/src/database/sql/driver/types.go?s=1210:1293#L29,
Valuer}
@item Alias validation tags, which allows for mapping of several validations
to a single tag for easier defining of validations on structs
@item Extraction of custom defined Field Name e.g. can specify to extract the
JSON name while validating and have it available in the resulting FieldError
@item Customizable i18n aware error messages.
@item Default validator for the @uref{https://github.com/gin-gonic/gin, gin}

supported).  For ARM CPUs with the Cryptography Extensions, advantage is taken
of the SHA2 instructions resulting in a massive performance improvement.

This package uses Golang assembly.  The AVX512 version is based on the Intel's

Usage is simple, just call homedir.Dir() to get the home directory for a user,
and homedir.Expand() to expand the @command{~} in a path to the home
directory.

Why not just use @command{os/user}?  The built-in @command{os/user} package
requires cgo on Darwin systems.  This means that any Go code that uses that
package cannot cross compile.  But 99% of the time the use for
@command{os/user} is just to retrieve the home directory, which we can do for
the current user without cgo.  This library does that, enabling
cross-compilation.")

simultaneously).  However, you may also create a new separate set of locks
test.

All locks are implemented with read-write mutexes.  To use them like a regular
mutex, simply ignore the RLock/RUnlock functions.")
