Struct NameError

pub struct NameError { /* private fields */ }

Name error.

Implementations

impl NameError

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"
);

Trait Implementations

impl Clone for NameError

fn clone(&self) -> NameError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NameError

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

Formats the value using the given formatter.

impl Display for NameError

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

Formats the value using the given formatter.

impl Error for NameError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for NameError

fn eq(&self, other: &NameError) -> 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.
