Enum UnknownChildPolicy

pub enum UnknownChildPolicy {
    Discard,
    Fail,
}

Control how unknown children are handled.

The variants of this enum are referenced in the #[xml(on_unknown_child = ..)] which can be used on structs and enum variants. The specified variant controls how children, which are not handled by any member of the compound, are handled during parsing.

Variants

Discard

All unknown children are discarded.

Fail

The first unknown child which is encountered generates a fatal parsing error.

This is the default policy.

Trait Implementations

impl Clone for UnknownChildPolicy

fn clone(&self) -> UnknownChildPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownChildPolicy

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

Formats the value using the given formatter.

impl Default for UnknownChildPolicy

fn default() -> UnknownChildPolicy

Returns the “default value” for a type.

impl Hash for UnknownChildPolicy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for UnknownChildPolicy

fn cmp(&self, other: &UnknownChildPolicy) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for UnknownChildPolicy

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

impl PartialOrd for UnknownChildPolicy

fn partial_cmp(&self, other: &UnknownChildPolicy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
