Struct webc::wasmer_package::Volume

pub struct Volume { /* private fields */ }

Available on crate feature package only.

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.

pub fn name(&self) -> &str

Returns the name of the volume

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

Trait Implementations

impl Clone for Volume

fn clone(&self) -> Volume

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Volume

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

Formats the value using the given formatter.

impl PartialEq for Volume

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

This method tests for self and other values to be equal, and is used by ==.

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

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