Struct MountOptions 

pub struct MountOptions {
    pub readonly: bool,
    pub noexec: bool,
    pub nosuid: bool,
    pub nodev: bool,
}

Guest mount behavior shared by every volume mount kind.

Fields

readonly: bool

Whether the mount is read-only.

Guest writes fail with the kernel’s read-only filesystem behavior. Virtiofs-backed mounts also reject writes on the host-side filesystem server as defense in depth.

noexec: bool

Whether direct execution from the mount is disabled.

This prevents execve of binaries or scripts located on the mount. Interpreters can still read files from the mount, for example sh /mnt/script.sh, because the interpreter itself executes from a different filesystem.

nosuid: bool

Whether setuid and setgid privilege elevation from files on the mount is ignored.

nodev: bool

Whether device files on the mount are ignored.

Trait Implementations

impl Clone for MountOptions

fn clone(&self) -> MountOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MountOptions

impl Debug for MountOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MountOptions

fn default() -> MountOptions

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MountOptions

where MountOptions: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MountOptions

impl PartialEq for MountOptions

fn eq(&self, other: &MountOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for MountOptions

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
