Trait Split

pub trait Split<Prefix>: VariadicExt + Sealed<Prefix>
where
    Prefix: VariadicExt,
{
    type Suffix: VariadicExt;

    // Required methods
    fn split(self) -> (Prefix, Self::Suffix);
    fn split_ref(
        this: Self::AsRefVar<'_>,
    ) -> (Prefix::AsRefVar<'_>, <Self::Suffix as VariadicExt>::AsRefVar<'_>);
}

Helper trait for splitting a variadic into two parts. Prefix is the first part, everything after is the Suffix or second part.

This is a sealed trait.

Required Associated Types

type Suffix: VariadicExt

The second part when splitting this variadic by Prefix.

Required Methods

fn split(self) -> (Prefix, Self::Suffix)

Splits this variadic into two parts, first the Prefix, and second the Suffix.

fn split_ref( this: Self::AsRefVar<'_>, ) -> (Prefix::AsRefVar<'_>, <Self::Suffix as VariadicExt>::AsRefVar<'_>)

Splits a refvar variadic

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<Item, Rest, PrefixRest> Split<(Item, PrefixRest)> for (Item, Rest)

where PrefixRest: VariadicExt, Rest: Split<PrefixRest>,

type Suffix = <Rest as Split<PrefixRest>>::Suffix

The second part when splitting this variadic by Prefix.

fn split(self) -> ((Item, PrefixRest), Self::Suffix)

Splits this variadic into two parts, first the Prefix, and second the Suffix.

fn split_ref( this: Self::AsRefVar<'_>, ) -> (<(Item, PrefixRest) as VariadicExt>::AsRefVar<'_>, <Self::Suffix as VariadicExt>::AsRefVar<'_>)

Splits a refvar variadic
