Struct TargetPath 

pub struct TargetPath(/* private fields */);

Wrapper for the virtual path to a target.

Implementations

impl TargetPath

pub fn new<P: Into<String>>(path: P) -> Result<Self>

Create a new TargetPath from a String.

assert!(TargetPath::new("foo").is_ok());
assert!(TargetPath::new("/foo").is_err());
assert!(TargetPath::new("../foo").is_err());
assert!(TargetPath::new("foo/..").is_err());
assert!(TargetPath::new("foo/../bar").is_err());
assert!(TargetPath::new("..foo").is_ok());
assert!(TargetPath::new("foo/..bar").is_ok());
assert!(TargetPath::new("foo/bar..").is_ok());

pub fn components(&self) -> Vec<String>

Split TargetPath into components that can be joined to create URL paths, Unix paths, or Windows paths.

let path = TargetPath::new("foo/bar").unwrap();
assert_eq!(path.components(), ["foo".to_string(), "bar".to_string()]);

pub fn is_child(&self, parent: &Self) -> bool

Return whether this path is the child of another path.

let path1 = TargetPath::new("foo").unwrap();
let path2 = TargetPath::new("foo/bar").unwrap();
assert!(!path2.is_child(&path1));

let path1 = TargetPath::new("foo/").unwrap();
let path2 = TargetPath::new("foo/bar").unwrap();
assert!(path2.is_child(&path1));

let path2 = TargetPath::new("foo/bar/baz").unwrap();
assert!(path2.is_child(&path1));

let path2 = TargetPath::new("wat").unwrap();
assert!(!path2.is_child(&path1))

pub fn matches_chain(&self, parents: &[HashSet<TargetPath>]) -> bool

Whether or not the current target is available at the end of the given chain of target paths. For the chain to be valid, each target path in a group must be a child of of all previous groups.

pub fn with_hash_prefix(&self, hash: &HashValue) -> Result<TargetPath>

Prefix the target path with a hash value to support TUF spec 5.5.2.

pub fn as_str(&self) -> &str

The string value of the path.

Trait Implementations

impl Borrow<str> for TargetPath

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Clone for TargetPath

fn clone(&self) -> TargetPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TargetPath

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TargetPath

fn deserialize<D: Deserializer<'de>>(de: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for TargetPath

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

Formats the value using the given formatter.

impl Hash for TargetPath

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

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 Ord for TargetPath

fn cmp(&self, other: &TargetPath) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TargetPath

fn eq(&self, other: &TargetPath) -> 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 PartialOrd for TargetPath

fn partial_cmp(&self, other: &TargetPath) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TargetPath

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
