Struct ListVTable 

#[repr(C)]
pub struct ListVTable {
    pub len: ListLenFn,
    pub get: ListGetFn,
    pub get_mut: Option<ListGetMutFn>,
    pub as_ptr: Option<ListAsPtrFn>,
    pub as_mut_ptr: Option<ListAsMutPtrFn>,
}

Virtual table for shareable list operations.

These operations can be type-erased and shared across all instantiations of a generic list type (e.g., one vtable for all Vec<T>). They work using runtime shape information to compute element offsets.

Per-type operations that cannot be shared (init, push, iterator) live in ListTypeOps.

Fields

len: ListLenFn

cf. ListLenFn

get: ListGetFn

get_mut: Option<ListGetMutFn>

cf. ListGetMutFn Only available for mutable lists

as_ptr: Option<ListAsPtrFn>

cf. ListAsPtrFn Only available for types that can be accessed as a contiguous array

as_mut_ptr: Option<ListAsMutPtrFn>

cf. ListAsMutPtrFn Only available for types that can be accessed as a contiguous array
