A name in GraphQL.

https://facebook.github.io/graphql/#sec-Names

An invalid name.

Create a Name.

Names must match the regex [_A-Za-z][_0-9A-Za-z]*. If the given text does not match, return Nothing.

>>> makeName "foo"
Right (Name {unName = "foo"})
>>> makeName "9-bar"
Left (NameError "9-bar")

Convert a type-level Symbol into a GraphQL Name.

Types that implement this have values with a single canonical name in a GraphQL schema.

e.g. a field foo(bar: Int32) would have the name "foo".

If a thing *might* have a name, or has a name that might not be valid, don't use this.

If a thing is aliased, then return the *original* name.

Create a Name, panicking if the given text is invalid.

Prefer makeName to this in all cases.

>>> unsafeMakeName "foo"
Name {unName = "foo"}
