Struct Dir

Source 
pub struct Dir {
    pub dir: Arc<Dir>,
    pub perms: DirPerms,
    pub file_perms: FilePerms,
    pub open_mode: OpenMode,
    /* private fields */
}

Fields§

§dir: Arc<Dir>

The operating system file descriptor this struct is mediating access to.

Wrapped in an Arc because a copy is needed for spawn_blocking.

§perms: DirPerms

Permissions to enforce on access to this directory. These permissions are specified by a user of the crate::WasiCtxBuilder, and are enforced prior to any enforced by the underlying operating system.

These permissions are also enforced on any directories opened under this directory.

§file_perms: FilePerms

Permissions to enforce on any files opened under this directory.

§open_mode: OpenMode

The mode the directory was opened under: bits for reading, and writing. Required to correctly report the DescriptorFlags, because cap-std doesn’t presently provide a cross-platform equivalent of reading the oflags back out using fcntl.
