Struct Namespace

pub struct Namespace { /* private fields */ }

The namespace of a component instance.

Namespaces may be represented as a collection of directory client endpoints and their corresponding unique paths, so called “flat representation”. In this case each path must be a valid cm_types::NamespacePath, and no path can be a parent of another path.

See https://fuchsia.dev/fuchsia-src/concepts/process/namespaces for the definition of namespaces of a process. The namespace of a component largely follows except that some more characters are disallowed (c.f. cm_types::NamespacePath documentation).

Implementations

impl Namespace

pub fn new() -> Self

pub fn add( &mut self, path: &NamespacePath, directory: ClientEnd<DirectoryMarker>, ) -> Result<(), NamespaceError>

pub fn get(&self, path: &NamespacePath) -> Option<&ClientEnd<DirectoryMarker>>

pub fn remove( &mut self, path: &NamespacePath, ) -> Option<ClientEnd<DirectoryMarker>>

pub fn flatten(self) -> Vec<Entry>

pub fn paths(&self) -> Vec<NamespacePath>

Get a copy of the paths in the namespace.

Trait Implementations

impl Clone for Namespace

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Namespace

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

Formats the value using the given formatter.

impl Default for Namespace

fn default() -> Self

Returns the “default value” for a type.

impl From<Namespace> for Vec<ComponentNamespaceEntry>

fn from(namespace: Namespace) -> Self

Converts to this type from the input type.

impl From<Namespace> for Vec<Entry>

fn from(namespace: Namespace) -> Self

Converts to this type from the input type.

impl From<Namespace> for Vec<NameInfo>

fn from(namespace: Namespace) -> Self

Converts to this type from the input type.

impl From<Namespace> for Vec<NamespaceEntry>

fn from(namespace: Namespace) -> Self

Converts to this type from the input type.

impl From<Tree<ClientEnd<DirectoryMarker>>> for Namespace

fn from(tree: Tree<ClientEnd<DirectoryMarker>>) -> Self

Converts to this type from the input type.

impl TryFrom<Namespace> for Arc<Simple>

Converts the Namespace into a vfs directory.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(namespace: Namespace) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Namespace> for TreeBuilder

Converts the Namespace to a vfs [TreeBuilder] with tree nodes for each entry.

The TreeBuilder can then be used to build a vfs directory for this Namespace.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(namespace: Namespace) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<ComponentNamespaceEntry>> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from(entries: Vec<ComponentNamespaceEntry>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<Entry>> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from(value: Vec<Entry>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<NameInfo>> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from(entries: Vec<NameInfo>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<NamespaceEntry>> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from(entries: Vec<NamespaceEntry>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Vec<NamespaceEntry>> for Namespace

type Error = NamespaceError

The type returned in the event of a conversion error.

fn try_from(entries: Vec<NamespaceEntry>) -> Result<Self, Self::Error>

Performs the conversion.
