Type Alias CowStr 

pub type CowStr = Cow<'static, str>;

Cow<'static, str>.

buildstructor doesn’t support Into<_> for types with parameters (like Cow<'static, str>), so we trick it by defining a type alias.

Aliased Type

pub enum CowStr {
    Borrowed(&'static str),
    Owned(String),
}

Variants

Borrowed(&'static str)

Borrowed data.

Owned(String)

Owned data.
