Crate dync

Overview

This crate aims to fill the gap in Rust’s dynamic traits system by exposing the control over dynamic virtual function tables to the user in a safe API. Below is a list of capabilities unlocked by dync.

• Create homogeneous untyped Vecs that store a single virtual function table for all contained elements. This functionality is enabled by the traits feature. For more details see vec_dyn.

Re-exports

• pub use downcast_rs as downcast;
• pub use index_slice::*;

Modules

• index_slice
• macros
  Utility macros for code generation.
• traits
  This module defines the function pointers for supported traits from the standard library.

Macros

• call_numeric_buffer_fn
  Applies $fn to an VecCopy mapping valid numeric data types by corresponding generic parameters. For example, passing an VecCopy containing data of type u8 will cause this macro to call $fn with type parameter u8 like $fn::<u8>(buffer).
• eval_align
• from_dyn
  Convert a given container with a dynamic vtable to a concrete type.
• into_dyn
  Convert a given container type (e.g. VecCopy or SliceDyn) to have a dynamic VTable.

Structs

• CopyValueMut
  A generic mutable Copy value reference.
• CopyValueRef
  A generic value reference to a Copy type.
• Meta
  Defines a meta struct containing information about a type but not the type itself.
• Slice
• SliceCopy
• SliceCopyMut
• SliceMut
• Value
• ValueMut
  A generic mutable value reference into a buffer.
• ValueRef
  A generic value reference into a buffer.
• VecCopy
  Buffer of untyped Copy values.
• VecDyn

Enums

• Error
• VTableRef
  A VTable reference type.

Traits

• CopyElem
• DropAsAligned
• Elem
• GetBytesMut
• GetBytesRef
• VTable
  VTable defines a type that represents a virtual function table for some type T.

Type Aliases

• BoxValue
• SliceDrop
• SliceMutDrop
• SmallValue
