Enum FromStrError

pub enum FromStrError {
    ShortInput,
    LongString,
    BadEscape,
    BadSymbol(Symbol),
}

An error happened when converting a Rust string to a DNS character string.

Variants

ShortInput

The string ended when there should have been more characters.

This most likely happens inside escape sequences and quoting.

LongString

A character string has more than 255 octets.

BadEscape

An illegal escape sequence was encountered.

Escape sequences are a backslash character followed by either a three decimal digit sequence encoding a byte value or a single other printable ASCII character.

BadSymbol(Symbol)

An illegal character was encountered.

Only printable ASCII characters are allowed.

Trait Implementations

impl Clone for FromStrError

fn clone(&self) -> FromStrError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FromStrError

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

Formats the value using the given formatter.

impl Display for FromStrError

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

Formats the value using the given formatter.

impl Fail for FromStrError

fn name(&self) -> Option<&str>

Returns the “name” of the error.

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

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D>

where D: Display + Send + Sync + 'static, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>

where Self: Sized,

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl From<BadSymbol> for FromStrError

fn from(err: BadSymbol) -> FromStrError

Converts to this type from the input type.

impl From<PushError> for FromStrError

fn from(_: PushError) -> FromStrError

Converts to this type from the input type.

impl From<SymbolError> for FromStrError

fn from(err: SymbolError) -> FromStrError

Converts to this type from the input type.

impl PartialEq for FromStrError

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