Enum VirtualPath 

pub enum VirtualPath {
    Virtual {
        path: PathBuf,
        virtual_prefix: PathBuf,
        real_prefix: PathBuf,
    },
    Real(PathBuf),
}

A container for WASI virtual paths that can also keep a reference to the original real path.

Variants

Virtual

A virtual path with prefixes to determine a real path.

Fields

path: PathBuf

virtual_prefix: PathBuf

real_prefix: PathBuf

Real(PathBuf)

Only a real path. Could not be matched with a virtual prefix.

Implementations

impl VirtualPath

pub fn exists(&self) -> bool

Inherited from Path::exists.

pub fn has_root(&self) -> bool

Inherited from Path::has_root.

pub fn is_absolute(&self) -> bool

Inherited from Path::is_absolute.

pub fn is_dir(&self) -> bool

Inherited from Path::is_dir.

pub fn is_file(&self) -> bool

Inherited from Path::is_file.

pub fn is_relative(&self) -> bool

Inherited from Path::is_relative.

pub fn extension(&self) -> Option<&OsStr>

Inherited from Path::extension.

pub fn file_name(&self) -> Option<&OsStr>

Inherited from Path::file_name.

pub fn file_stem(&self) -> Option<&OsStr>

Inherited from Path::file_stem.

pub fn set_extension(&mut self, value: impl AsRef<OsStr>)

Inherited from PathBuf::set_extension.

pub fn set_file_name(&mut self, value: impl AsRef<OsStr>)

Inherited from PathBuf::set_file_name.

pub fn ends_with(&self, value: impl AsRef<Path>) -> bool

Inherited from Path::ends_with.

pub fn starts_with(&self, value: impl AsRef<Path>) -> bool

Inherited from Path::starts_with.

pub fn join<P>(&self, path: P) -> VirtualPath

where P: AsRef<Path>,

Append the path part and return a new VirtualPath instance.

pub fn parent(&self) -> Option<VirtualPath>

Return the parent directory as a new VirtualPath instance.

pub fn any_path(&self) -> &PathBuf

Return any path available, either virtual or real, regardless of any conditions. This is primarily used for debugging.

pub fn real_path(&self) -> Option<PathBuf>

Return the original real path. If we don’t have access to prefixes, or removing prefix fails, returns None.

pub fn real_path_string(&self) -> Option<String>

Return the original real path as a string.

pub fn to_path_buf(&self) -> PathBuf

Convert the virtual path into a PathBuf instance. This does not convert it into a real path.

pub fn virtual_path(&self) -> Option<PathBuf>

Return the virtual path. If a real path only, returns None.

pub fn virtual_path_string(&self) -> Option<String>

Return the virtual path as a string.

pub fn without_prefix(&self) -> Option<&Path>

Return the current path without a virtual prefix. If we don’t have access to prefixes, returns None.

Trait Implementations

impl AsRef<OsStr> for VirtualPath

fn as_ref(&self) -> &OsStr

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<Path> for VirtualPath

fn as_ref(&self) -> &Path

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<PathBuf> for VirtualPath

fn as_ref(&self) -> &PathBuf

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<VirtualPath> for VirtualPath

fn as_ref(&self) -> &VirtualPath

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for VirtualPath

fn clone(&self) -> VirtualPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VirtualPath

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

Formats the value using the given formatter.

impl Default for VirtualPath

fn default() -> VirtualPath

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VirtualPath

fn deserialize<__D>( __deserializer: __D, ) -> Result<VirtualPath, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VirtualPath

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

Formats the value using the given formatter.

impl Hash for VirtualPath

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VirtualPath

fn eq(&self, other: &VirtualPath) -> 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 VirtualPath

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
