From 24b0e91d8096f84a114f662e3eb42c83d0d3878d Mon Sep 17 00:00:00 2001 From: Bert Belder Date: Mon, 9 Jul 2018 03:35:34 +0200 Subject: Move buffers between V8 and native * send()/recv() now operate on TypedArrays rather than ArrayBuffers. * Remove a copy (through ArrayBuffer.slice()) from the send path. * Remove a copy (through v8::ArrayBuffer::New()) from the return path. * After moving a buffer from JS to native, the ArrayBuffer object and it's views are made inaccessible ('neutered'). * `struct deno_buf` now holds two [ptr, length] tuples, one for the actual memory allocation, and one for the logical data contained therein. This is necessary because flatbuffers fills it's buffer bottom-up, so the serialized blob doesn't start at beginning of the buffer, but somewhere in the middle. --- src/main.rs | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) (limited to 'src/main.rs') diff --git a/src/main.rs b/src/main.rs index ece311a4f..2755a3a9c 100644 --- a/src/main.rs +++ b/src/main.rs @@ -9,8 +9,10 @@ use std::ptr; #[repr(C)] struct deno_buf { - data: *const c_char, - len: c_int, // TODO(ry) should be size_t. + alloc_ptr: *mut u8, + alloc_len: usize, + data_ptr: *mut u8, + data_len: usize, } #[repr(C)] @@ -120,9 +122,10 @@ fn main() { let mut d = Deno::new(); - d.execute("deno_main.js", "denoMain();") - .unwrap_or_else(|err| { + d.execute("deno_main.js", "denoMain();").unwrap_or_else( + |err| { println!("Error {}\n", err); std::process::exit(1); - }); + }, + ); } -- cgit v1.2.3
