Struct dbus_message_parser::value::ObjectPath

pub struct ObjectPath(_);

This represents a object path.

Implementations

impl ObjectPath

pub fn append(&mut self, element: &str) -> bool

Append an element to the object path.

Returns true if the new element could be appended, otherwise false. An element cannot be appended if the element contain a character, which is not allowed.

Example

let mut object_path = ObjectPath::try_from("/object").unwrap();

assert!(object_path.append("path"));
assert!(!object_path.append("/path"));

assert_eq!(&object_path, "/object/path");

pub fn starts_with(&self, base: &ObjectPath) -> bool

Determines whether base is a prefix of self.

Example

let base = ObjectPath::try_from("/object").unwrap();

let path_1 = ObjectPath::try_from("/object/path").unwrap();
let path_2 = ObjectPath::try_from("/object_/path").unwrap();

assert!(path_1.starts_with(&base));
assert!(!path_2.starts_with(&base));
assert!(!base.starts_with(&base));

pub fn strip_prefix_elements<'a, 'b>(
    &'a self,
    base: &'b ObjectPath
) -> Option<Split<'a, char>>

Returns a Split object with the prefix removed.

Example

let base = ObjectPath::try_from("/object").unwrap();

let path_1 = ObjectPath::try_from("/object/path").unwrap();
let path_2 = ObjectPath::try_from("/object_/path").unwrap();
let path_3 = ObjectPath::try_from("/object/path/element").unwrap();

let path_1_base_vec: Vec<&str> = path_1.strip_prefix_elements(&base).unwrap().collect();
let path_3_base_vec: Vec<&str> = path_3.strip_prefix_elements(&base).unwrap().collect();

assert_eq!(path_1_base_vec, vec!["path"]);
assert!(path_2.strip_prefix_elements(&base).is_none());
assert_eq!(path_3_base_vec, vec!["path", "element"]);
assert!(base.strip_prefix_elements(&base).is_none());
