Enum smartcow::SmartCow

pub enum SmartCow<'a> {
    Borrowed(&'a str),
    Owned(SmartString<LazyCompact>),
}

The primary type for this crate, which holds either a borrowed str or a SmartString

Variants

Borrowed

a std::str borrow

Tuple Fields of Borrowed

0: &'a str

Owned

a smartstring::SmartString

Tuple Fields of Owned

0: SmartString<LazyCompact>

Implementations

impl SmartCow<'_>

pub fn to_owned(&self) -> SmartCow<'static>

Build a ’static duplicate of this SmartCow by cloning a reference. If you own the SmartCow, SmartCow::into_owned is preferable, as it will not allocate an unnecesssary owned value.

This is identical to calling self.clone().into_owned(), which first allocates in the case of an owned variant by cloning, and then allocates in the case of a borrowed variant, with into_owned.

pub fn into_owned(self) -> SmartCow<'static>

Build a ’static duplicate of this SmartCow by value, by allocating a SmartString if self is a SmartCow::Borrowed variant. If you do not have ownership of a SmartCow and need to create a ’static SmartCow from it by reference, use SmartCow::to_owned
