Struct File 

pub struct File {
    pub file: Arc<File>,
    pub perms: FilePerms,
    pub open_mode: OpenMode,
    /* private fields */
}

Fields

file: Arc<File>

The operating system File this struct is mediating access to.

Wrapped in an Arc because the same underlying file is used for implementing the stream types. A copy is also needed for spawn_blocking.

perms: FilePerms

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

open_mode: OpenMode

The mode the file 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.

Implementations

fn clone_from(&mut self, source: &Self)
