[−][src]Crate cervine
cervine::Cow
is an alloc::borrow::Cow
alternative that has different generic type constraints.
Features
"serde"
: Implements serde::Deserialize
and serde::Serialize
on Cow
.
Examples
Same type (T = R = [bool; 2]
):
use cervine::Cow; use rand::prelude::*; use std::borrow::Borrow as _; let data = [true, false]; let mut cow = Cow::Borrowed(&data); if thread_rng().gen() { cow = Cow::Owned([false, true]); } let array_ref: &[bool; 2] = cow.borrow();
Different types (T = String
and R = str
):
use cervine::Cow; use rand::prelude::*; use smartstring::alias::String; let mut cow = Cow::Borrowed("borrowed"); if thread_rng().gen() { cow = Cow::Owned(String::from("owned")); } let str_ref: &str = cow.as_ref();
