Struct FsVolume

pub struct FsVolume { /* private fields */ }

A lazily loaded volume in a Wasmer package.

Note that it is the package resolver’s role to interpret a package’s [crate::metadata::annotations::FileSystemMappings]. A [Volume] contains directories as they were when the package was published.

Implementations

impl FsVolume

pub fn name(&self) -> &str

Returns the name of the volume

pub fn read_file(&self, path: &PathSegments) -> Option<OwnedBuffer>

Read a file from the volume.

pub fn read_dir( &self, path: &PathSegments, ) -> Option<Vec<(PathSegment, Option<[u8; 32]>, Metadata)>>

Read the contents of a directory.

pub fn metadata(&self, path: &PathSegments) -> Option<Metadata>

Get the metadata for a particular item.

Trait Implementations

impl AbstractVolume for FsVolume

fn read_file( &self, path: &PathSegments, ) -> Option<(OwnedBuffer, Option<[u8; 32]>)>

Returnes the contents of the file associated with path and optionally, its hash

fn read_dir( &self, path: &PathSegments, ) -> Option<Vec<(PathSegment, Option<[u8; 32]>, Metadata)>>

Returns the entries of path

fn metadata(&self, path: &PathSegments) -> Option<Metadata>

Returns the metadata of the entry associated with path

impl Clone for FsVolume

fn clone(&self) -> FsVolume

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FsVolume

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

Formats the value using the given formatter.

impl PartialEq for FsVolume

fn eq(&self, other: &FsVolume) -> 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 WasmerPackageVolume for FsVolume

fn as_directory_tree( &self, strictness: Strictness, ) -> Result<Directory<'_>, Error>

Serialize the volume as a webc::v3::write::Directory.

fn as_volume(self: Arc<Self>) -> Arc<dyn AbstractVolume + Send + Sync + 'static>
