Struct AsAsciiStrError

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

Error that is returned when a sequence of u8 are not all ASCII.

Is used by As[Mut]AsciiStr and the from_ascii method on AsciiStr and AsciiString.

Implementations

impl AsAsciiStrError

pub fn valid_up_to(self) -> usize

Returns the index of the first non-ASCII byte.

It is the maximum index such that from_ascii(input[..index]) would return Ok(_).

Trait Implementations

impl Clone for AsAsciiStrError

fn clone(&self) -> AsAsciiStrError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AsAsciiStrError

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

Formats the value using the given formatter.

impl Display for AsAsciiStrError

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

Formats the value using the given formatter.

impl Error for AsAsciiStrError

fn description(&self) -> &'static str

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

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

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

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 AsAsciiStrError

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