Enum ResolvedMount 

#[non_exhaustive]
pub enum ResolvedMount {
    Tmpfs {
        target: PathBuf,
        flags: u64,
        data: String,
    },
    Procfs {
        target: PathBuf,

        read_only: bool,
    },
    Raw {
        source: Option<PathBuf>,
        target: PathBuf,
        fstype: Option<String>,
        flags: u64,
        data: Option<String>,
    },
    Symlink {
        path: PathBuf,
        target: PathBuf,
    },
}

One mount a built sandbox will establish.

The resolved counterpart of Mount: where that records what a caller declared, this records every mount the sandbox performs, including the ones the managed profile contributes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Tmpfs

A tmpfs.

Fields

target: PathBuf

The mount point inside the sandbox.

flags: u64

The kernel’s raw MS_* flags.

data: String

The filesystem data string.

Procfs

A procfs instance.

Fields

target: PathBuf

The mount point inside the sandbox.

Devpts

A devpts instance.

Fields

target: PathBuf

The mount point inside the sandbox.

data: String

The filesystem data string.

Bind

A bind of a host path.

Fields

source: PathBuf

The host path bound in.

target: PathBuf

The mount point inside the sandbox.

read_only: bool

Whether the bind is remounted read-only.

Raw

A mount whose parameters go to the kernel verbatim.

The optional fields report None both for a parameter that was never set and for one set to the empty string: the two are frozen alike, and the kernel receives the same nothing from either.

Fields

source: Option<PathBuf>

The mount source, when one was given.

target: PathBuf

The mount point inside the sandbox.

fstype: Option<String>

The filesystem type, when one was given.

flags: u64

The kernel’s raw MS_* flags.

data: Option<String>

The filesystem data string, when one was given.

Symlink

A symlink created inside the rootfs.

Not a mount in the kernel’s sense, but part of what the managed profile establishes — the five /dev symlinks arrive this way — and so part of the filesystem the command sees.

Fields

path: PathBuf

The link’s own path inside the sandbox.

target: PathBuf

The path the link points at, as written.

Implementations

impl ResolvedMount

pub fn get_target(&self) -> &Path

The path inside the sandbox this mount is established at.

For a Symlink this is the link itself, not the path it points at.

Trait Implementations

impl Clone for ResolvedMount

fn clone(&self) -> ResolvedMount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolvedMount

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

Formats the value using the given formatter.

impl Eq for ResolvedMount

impl PartialEq for ResolvedMount

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for ResolvedMount

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
