Enum OptimalStringType 

pub enum OptimalStringType {
    StaticStr,
    BorrowedStr {
        lifetime: Option<String>,
    },
    OwnedString,
    CowStr,
}

Optimal string representation based on usage analysis

Variants

StaticStr

Use &’static str for string literals that are never mutated

BorrowedStr

Use &str for borrowed string parameters

Fields

lifetime: Option<String>

OwnedString

Use String for owned, mutable strings

CowStr

Use Cow<’static, str> for mixed usage patterns

Trait Implementations

impl Clone for OptimalStringType

fn clone(&self) -> OptimalStringType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimalStringType

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

Formats the value using the given formatter.

impl PartialEq for OptimalStringType

fn eq(&self, other: &OptimalStringType) -> 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.
