Crate gidl_util

This crate contains utility functions used in GIDL tests and benchmarks.

Structs

• HandleDef
  Specifies a handle to be created with create_handles. Corresponds to HandleDef in //tools/fidl/gidl/ir/test_case.go.

Enums

• HandleSubtype
  Handle subtypes that can be created via create_handles. Each subtype X corresponds to a fidl::X type that implements HandleBased.

Functions

• copy_handle
  Copies a raw handle into an owned HandleBased handle.
• create_handles
  Creates a vector of raw handles based on defs. Panics if creating any of the handles fails. The caller is responsible for closing the handles.
• decode_value
  Decodes T from the given bytes and handles. Panics on failure.
• get_handle_koid
  Gets the koid of a handle from its raw handle info. Panics if the zx_object_get_info syscall fails.
• get_info_handle_valid
  Returns the result of the zx_object_get_info syscall with topic ZX_INFO_HANDLE_VALID. In particular, returns Status::BAD_HANDLE if the handle is dangling because it was already closed or never assigned to the process in the first place.
• repeat
  Returns a vector of value repeated len times.
• select_handle_infos
  Copies raw handles from the given indices to a new vector of owned HandleInfos. The caller must ensure handles are closed exactly once.
• select_raw_handle_infos
  Copies raw handles from the given indices to a new vector.
• to_zx_handle_disposition_t
  Converts a HandleDisposition to a raw zx_handle_disposition_t.
