Enum OptimizedString 

pub enum OptimizedString {
    Static(&'static str),
    Interned(Arc<str>),
    Small(FastString),
    Atom(DefaultAtom),
}

Optimized string for DDEX data

Variants

Static(&'static str)

Static string reference (zero allocation)

Interned(Arc<str>)

Interned string (shared allocation)

Small(FastString)

Small string optimization

Atom(DefaultAtom)

Atom for very frequent lookups

Implementations

impl OptimizedString

pub fn new(s: &str) -> Self

Create from a string, choosing the most efficient representation

pub fn interned(s: Arc<str>) -> Self

Create from an interned string

pub fn atom(atom: DefaultAtom) -> Self

Create from an atom

pub fn as_str(&self) -> &str

Get the string value

pub fn memory_footprint(&self) -> usize

Get memory footprint in bytes

Trait Implementations

impl AsRef<str> for OptimizedString

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for OptimizedString

fn clone(&self) -> OptimizedString

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OptimizedString

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for OptimizedString

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for OptimizedString

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OptimizedString

fn eq(&self, other: &OptimizedString) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
