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.
