Crate optee_utee 

TEE internal core API.

Feature flags

• default — enables nothing.
• std — enables the ability to use the standard library.
• no_panic_handler — disables the default panic handler (which calls TEE_Panic), allowing TA developers to provide a custom #[panic_handler].
• unwind_stubs — provides linker stubs for _Unwind_Resume and rust_eh_personality. These are required by the precompiled sysroot when not using -Z build-std, even though panic=abort guarantees they are never called at runtime.
• doc — used for docs.rs to generate docs.

Macros

define_property_key

Macro to define a property key. This macro generates a struct that implements the PropertyKey trait.

trace_print

Macro for printing to the trace output, without a newline.

trace_println

Macro for printing to the trace output, with a newline. Use the format! syntax to write data to the standard output. See std::fmt for more information.

Structs

Error

ParameterMemrefInout

A memory-reference in/out parameter.

ParameterMemrefInput

A memory-reference input parameter.

ParameterMemrefOutput

A memory-reference output parameter.

ParameterNone

ParameterValueInout

A value-type in/out parameter.

ParameterValueInput

A value-type input parameter.

ParameterValueOutput

A value-type output parameter.

TaSession

TaSessionBuilder

TeeParams

The TeeParams struct is used to manage the parameters for TEE commands.

Enums

ErrorKind

A list specifying general categories of TEE error and its corresponding code in OP-TEE OS.

ParamIndex

ParamType

Enumerates the seven standard TEE parameter types.

ParameterAny

A type-erased parameter that dispatches to the correct concrete wrapper based on the runtime type tag.

Traits

FromRawParameter

Convert a single raw parameter into a type-safe Rust wrapper.

FromRawParameters

Convert all four raw parameters at once into a typed tuple.

ParameterMemref

Shared buffer length for a memory-reference parameter.

ParameterMemrefRead

Read-only access to a memory-reference parameter’s buffer.

ParameterMemrefWrite

Write access to a memory-reference parameter’s buffer.

ParameterValueRead

Read-only access to the two u32 fields of a value parameter.

ParameterValueWrite

Write access to the two u32 fields of a value parameter.

Type Aliases

ParametersAny

ParametersNone

RawParamType

Raw parameter-type tag as passed by the TEE runtime. Each of the four slots carries a 4-bit type-identifier. Use TEE_PARAM_TYPE_GET(raw_types, idx) to extract one slot from the RawParamTypes bit-field.

RawParamTypes

Together with a RawParams array this describes the name and content of all four TEE parameters.

RawParams

Array of four raw TEE_Param unions.

Result

A specialized Result type for TEE operations.

Attribute Macros

ta_close_session

Attribute to declare the entry point of closing a session. Session context raw pointer (*mut T) can be defined as an optional parameter.

ta_create

Attribute to declare the entry point of creating TA.

ta_destroy

Attribute to declare the entry point of destroying TA.

ta_invoke_command

Attribute to declare the entry point of invoking commands.

ta_open_session

Attribute to declare the entry point of opening a session.
