Struct ParamTmpRef 

pub struct ParamTmpRef<'a> { /* private fields */ }

This type defines a temporary memory reference. It is used as a Operation parameter when the corresponding parameter type is one of MemrefTempInput, MemrefTempOutput, or MemrefTempInout.

Implementations

impl<'a> ParamTmpRef<'a>

pub fn new_input(buffer: &'a [u8]) -> Self

Creates a temporary input only memory reference. buffer is a region of memory which needs to be temporarily registered for the duration of the Operation.

pub fn new_output(buffer: &'a mut [u8]) -> Self

Creates a temporary memory reference. buffer is a region of memory which needs to be temporarily registered for the duration of the Operation.

pub fn new_inout(buffer: &'a mut [u8]) -> Self

Creates a temporary input/output memory reference.

buffer is a region of memory which needs to be temporarily registered for the duration of the Operation and can be both read and written by the Trusted Application (TA).

This is useful when you need to pass data to a TA that will modify it and return the modified data in the same buffer.
