Description
I tried this code:
//! This is src/bin/metadata.rs.
//! Compiled to wasm32-unknown-emscripten.
//! My codes are in <https://github.com/TheVeryDarkness/wasm-emscripten-fs-bug>.
use std::fs::{create_dir, metadata, read_dir, write};
fn main() {
create_dir("workspace");
write("workspace/a.txt", "I'm a.\n").unwrap();
write("workspace/b.txt", "This is b.\n").unwrap();
for file in read_dir("workspace").unwrap() {
let file = file.unwrap();
println!("{:?}", file.path());
let meta = file.metadata().unwrap();
println!("{:?}", meta);
println!("{}", meta.len());
}
let meta = metadata("workspace").unwrap();
println!("{:?}", meta);
// This seems to be the same with permission code.
println!("{:?}", meta.file_type());
println!("{}", meta.is_dir());
println!("{}", meta.is_file());
println!("{}", meta.is_symlink());
}I expected to see this happen: got correct file_type() and len().
Instead, this happened: file_type() returns permission code, while len() returns created time..
