Enum cookie::CookieStr

pub(crate) enum CookieStr<'c> {
    Indexed(usize, usize),
    Concrete(Cow<'c, str>),
}

Variants

Indexed(usize, usize)

An string derived from indexes (start, end).

Concrete(Cow<'c, str>)

A string derived from a concrete string.

Implementations

impl<'c> CookieStr<'c>

pub(crate) fn indexed( needle: &str, haystack: &str, ) -> Option<CookieStr<'static>>

Creates an indexed CookieStr that holds the start and end indices of needle inside of haystack, if needle is a substring of haystack. Otherwise returns None.

The needle can later be retrieved via to_str().

pub(crate) fn to_str<'s>(&'s self, string: Option<&'s Cow<'_, str>>) -> &'s str

Retrieves the string self corresponds to. If self is derived from indices, the corresponding subslice of string is returned. Otherwise, the concrete string is returned.

Panics

Panics if self is an indexed string and string is None.

pub(crate) fn to_raw_str<'s, 'b: 's>( &'s self, string: &'s Cow<'b, str>, ) -> Option<&'b str>

pub(crate) fn into_owned(self) -> CookieStr<'static>

Trait Implementations

impl<'c> Clone for CookieStr<'c>

fn clone(&self) -> CookieStr<'c>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'c> Debug for CookieStr<'c>

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

Formats the value using the given formatter.
