Struct varlen::str::StrCloner

pub struct StrCloner<'a, Len: ArrayLen>(_);

Initializer type for cloning an array.

Prefer to use Str::vcopy() over Str::vclone() where possible.

Examples

use varlen::prelude::*;
let arr = VBox::new(Str::copy("hello"));
let seq: Seq<Str> = seq![arr.vclone(), arr.vclone(), arr.vclone()];  // Clones the string
for a in seq.iter() {
    assert_eq!(&a[..], "hello");
}

Trait Implementations

impl<'a, Len: ArrayLen> Initializer<Str<Len>> for StrCloner<'a, Len>

fn calculate_layout_cautious(&self) -> Option<<Str<Len> as VarLen>::Layout>

Calculates the layout of the object, returning None if any of the calculated sizes or offsets would overflow usize.

unsafe fn initialize(
    self,
    dst: NonNull<Str<Len>>,
    layout: <Str<Len> as VarLen>::Layout
)

Populates the destination pointer.
