Enum pingora_core::ImmutStr

pub enum ImmutStr {
    Static(&'static str),
    Owned(Box<str>),
}

A data struct that holds either immutable string or reference to static str. Compared to String or Box<str>, it avoids memory allocation on static str.

Variants

Static(&'static str)

Owned(Box<str>)

Trait Implementations

impl Clone for ImmutStr

fn clone(&self) -> ImmutStr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImmutStr

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

Formats the value using the given formatter.

impl Display for ImmutStr

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

impl From<&'static str> for ImmutStr

fn from(s: &'static str) -> ImmutStr

Converts to this type from the input type.

impl From<String> for ImmutStr

fn from(s: String) -> ImmutStr

Converts to this type from the input type.

impl PartialEq for ImmutStr

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

This method tests for self and other values to be equal, and is used by ==.

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

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