Crate crate_swap

Expand description

Defines functions and types for crate swapping, used in live evolution and fault recovery.

Structs

  • SwapRequest
    This struct is used to specify the details of a crate-swapping operation, in which an “old” crate is replaced with a “new” crate that is then used in place of that old crate. The old crate is removed from its old CrateNamespace while the new crate is added to the new CrateNamespace; typically the old and new namespaces are the same.

Enums

  • InvalidSwapRequest
    The possible errors that can occur when trying to create a valid SwapRequest.

Functions

  • clear_unloaded_crate_cache
    Clears the cache of unloaded (swapped-out) crates saved from previous crate swapping operations.
  • swap_crates
    Swaps in new crates that can optionally replace existing crates in this CrateNamespace.

Type Aliases

  • StateTransferFunction
    A state transfer function is an arbitrary function called when swapping crates.
  • SwapRequestList
    A list of one or more SwapRequests that is used by the swap_crates function.
