newtype AccessFlagBits Source #

VkAccessFlagBits - Bitmask specifying memory access types that will participate in a memory dependency

Description

These values all have the same meaning as the equivalently named values for AccessFlags2KHR.

Certain access types are only performed by a subset of pipeline stages. Any synchronization command that takes both stage masks and access masks uses both to define the access scopes - only the specified access types performed by the specified stages are included in the access scope. An application must not specify an access flag in a synchronization command if it does not include a pipeline stage in the corresponding stage mask that is able to perform accesses of that type. The following table lists, for each access flag, which pipeline stages can perform that type of access.
