Trait slotmap::Slottable [−][src]
pub trait Slottable: Copy { }
Expand description
A trait for items that can go in a slot map. Due to current stable Rust
restrictions a type must be Copy
to be placed in a slot map. If you must
store a type that is not Copy
you must use nightly Rust and enable the
unstable
feature for slotmap
by editing your Cargo.toml
.
slotmap = { version = "...", features = ["unstable"] }
This trait should already be automatically implemented for any type that is
slottable. If you can’t use unstable Rust and still want to store Copy
data, store that as associated data in a SecondaryMap
.
