Struct BenchmarksBlake3HashChunkArgs 

pub struct BenchmarksBlake3HashChunkArgs<'external_args> { /* private fields */ }

Data structure containing expected input for external method invocation, eventually calling benchmarks_blake3_hash_chunk() on the other side by the host.

This can be used with Env, though there are helper methods on this provided by extension trait that allow not dealing with this struct directly in simpler cases.

Implementations

impl<'external_args> BenchmarksBlake3HashChunkArgs<'external_args>

pub fn new( chunk: &'external_args [u8; 1024], ok_result: &'external_args mut MaybeUninit<[u8; 32]>, ) -> Self

Create a new instance.

A call can leave contents behind in outputs that are not valid values of their types, even when it succeeds. Hence outputs are given as OutputArg, which makes sure contents are parsed before they are accessed, unless every bit pattern is a valid value. After a successful call, query updated sizes of outputs with *_size() getters and set them with OutputArg::set_output_size(). The return value (if there is one) is initialized after a successful call, but it is not necessarily a valid value of its type and must be parsed, for example with IoType::try_from_ptr().
