Struct xml_string::names::NameError

pub struct NameError { /* fields omitted */ }

Name error.

Implementations

impl NameError

#[must_use]pub fn valid_up_to(&self) -> usize

Returns the index in the given string up to which valid name was verified.

Note that &source_str[..err.valid_up_to()] might be invalid when valid_up_to is zero. In other words, it depends on target type whether the empty string is valid or not. This error type does not assume anything about it.

Examples

use xml_string::names::Ncname;

let err_nonempty = Ncname::from_str("foo:bar").expect_err("NCName cannot have a colon");
assert_eq!(err_nonempty.valid_up_to(), 3);
assert!(Ncname::from_str("foo").is_ok());

let err_empty = Ncname::from_str("").expect_err("NCName cannot be empty");
assert_eq!(err_empty.valid_up_to(), 0);
assert!(
    Ncname::from_str("").is_err(),
    "Note that `&s[..err.valid_up_to()]` is not always valid for the empty source string"
);

impl Error for NameError

pub fn source(&self) -> Option<&(dyn Error + 'static)>

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()
