Struct optee_teec::Context

pub struct Context { /* fields omitted */ }

An abstraction of the logical connection between a client application and a TEE.

Implementations

impl Context

pub fn new() -> Result<Context>

Creates a TEE client context object.

Examples

let ctx = Context::new().unwrap();

pub fn new_raw(
    fd: c_int,
    reg_mem: bool,
    memref_null: bool
) -> Result<TEEC_Context>

Creates a raw TEE client context with implementation defined parameters.

Examples

let raw_ctx: optee_teec_sys::TEEC_Context = Context::new_raw(0, true).unwrap();

pub fn as_mut_raw_ptr(&mut self) -> *mut TEEC_Context

Converts a TEE client context to a raw pointer.

Examples

let mut ctx = Context::new().unwrap();
let mut raw_ptr: *mut optee_teec_sys::TEEC_Context = ctx.as_mut_raw_ptr();

pub fn open_session(&mut self, uuid: Uuid) -> Result<Session<'_>>

Opens a new session with the specified trusted application.

The target trusted application is specified by uuid.

Examples

let mut ctx = Context::new().unwrap();
let uuid = Uuid::parse_str("8abcf200-2450-11e4-abe2-0002a5d5c51b").unwrap();
let session = ctx.open_session(uuid).unwrap();

pub fn open_session_with_operation<A: Param, B: Param, C: Param, D: Param>(
    &mut self,
    uuid: Uuid,
    operation: &mut Operation<A, B, C, D>
) -> Result<Session<'_>>

Opens a new session with the specified trusted application, pass some parameters to TA by an operation.

The target trusted application is specified by uuid.

Examples

let mut ctx = Context::new().unwrap();
let uuid = Uuid::parse_str("8abcf200-2450-11e4-abe2-0002a5d5c51b").unwrap();
let p0 = ParamValue(42, 0, ParamType::ValueInout);
let mut operation = Operation::new(0, p0, ParamNone, ParamNone, ParamNone);
let session = ctx.open_session_with_operation(uuid, operation).unwrap();

Trait Implementations

fn drop(&mut self)

Executes the destructor for this type.
