Struct ParsedQname

pub struct ParsedQname<'a> { /* private fields */ }

Parsed QName reference.

Implementations

impl<'a> ParsedQname<'a>

pub fn from_str(s: &'a str) -> Result<Self, NameError>

Creates a new ParsedQname<'_> from the given string slice.

Failures

Fails if the given string is not a valid QName.

Examples

let noprefix = ParsedQname::from_str("hello")?;
assert_eq!(noprefix, "hello");

let prefixed = ParsedQname::from_str("foo:bar")?;
assert_eq!(prefixed, "foo:bar");

assert!(ParsedQname::from_str("").is_err(), "Empty string is not a QName");
assert!(ParsedQname::from_str("foo bar").is_err(), "Whitespace is not allowed");
assert!(ParsedQname::from_str("foo:bar:baz").is_err(), "Two or more colons are not allowed");
assert!(ParsedQname::from_str("0foo").is_err(), "ASCII digit at the beginning is not allowed");

pub fn as_qname(&self) -> &'a Qname

Returns the string as &Qname.

Exmaples

use xml_string::names::Qname;

let name = ParsedQname::from_str("hello")?;
assert_eq!(name, "hello");

let s: &Qname = name.as_qname();
assert_eq!(s, "hello");

pub fn as_str(&self) -> &'a str

Returns the string as &str.

Exmaples

let name = ParsedQname::from_str("hello")?;
assert_eq!(name, "hello");

let s: &str = name.as_str();
assert_eq!(s, "hello");

pub fn len(&self) -> usize

Returns the length of the string in bytes.

Examples

let name = ParsedQname::from_str("foo:bar")?;
assert_eq!(name.len(), 7);

pub fn has_prefix(&self) -> bool

Returns whether the QName has a prefix.

Examples

let local_only = ParsedQname::from_str("hello")?;
assert!(!local_only.has_prefix());

let prefixed = ParsedQname::from_str("foo:bar")?;
assert!(prefixed.has_prefix());

pub fn prefix(&self) -> Option<&'a Ncname>

Returns the prefix, if available.

Examples

let prefixed = ParsedQname::from_str("foo:bar")?;
assert_eq!(prefixed.prefix().map(|s| s.as_str()), Some("foo"));

let noprefix = ParsedQname::from_str("foo")?;
assert_eq!(noprefix.prefix().map(|s| s.as_str()), None);

pub fn local_part(&self) -> &'a Ncname

Returns the local part.

Examples

let prefixed = ParsedQname::from_str("foo:bar")?;
assert_eq!(prefixed.local_part(), "bar");

let noprefix = ParsedQname::from_str("foo")?;
assert_eq!(noprefix.local_part(), "foo");

pub fn prefix_and_local(&self) -> (Option<&'a Ncname>, &'a Ncname)

Returns a pair of the prefix (if available) and the local part.

This is efficient version of (self.prefix(), self.local_part()).

Examples

use std::convert::TryFrom;

let noprefix = ParsedQname::from_str("hello")?;
assert_eq!(noprefix.prefix_and_local(), (noprefix.prefix(), noprefix.local_part()));

let prefixed = ParsedQname::from_str("foo:bar")?;
assert_eq!(prefixed.prefix_and_local(), (prefixed.prefix(), prefixed.local_part()));
