Enum mail_headers::data::InnerUtf8

pub enum InnerUtf8 {
    Owned(String),
    Shared(OwningRef<Arc<String>, str>),
}

InnerUtf8 is string data container which can contain either a owned String or a str reference into a shared string buffer.

Variants

Owned(String)Shared(OwningRef<Arc<String>, str>)

Methods

impl InnerUtf8

pub fn into_shared(self) -> Self

converts this container into on which uses underlying shared data

if the data is already shared nothing is done. If not the owned data is converted into the underlying string buffer and OwningRef is used to enable the shared reference

impl InnerUtf8

pub fn new<S: Into<String>>(data: S) -> Self

impl InnerUtf8

pub fn as_str(&self) -> &str
