Struct QueryFileBasicInfo 

pub struct QueryFileBasicInfo { /* private fields */ }

An owned, marshalable parameter set for GetFileInformationByHandleEx with FileBasicInfo.

Example

use std::fs;

use windows_namespace_request_sys::file_basic::QueryFileBasicInfo;
use windows_sys::Win32::Storage::FileSystem::FILE_ATTRIBUTE_DIRECTORY;

let path = std::env::temp_dir().join(format!("wnrs-fb-{}.tmp", std::process::id()));
fs::write(&path, b"example")?;

let basic = QueryFileBasicInfo::new(fs::File::open(&path)?).perform()?;

// The attributes are the call's bits; a file is not a directory.
assert_eq!(basic.file_attributes() & FILE_ATTRIBUTE_DIRECTORY, 0);
