Struct ValidationFlags 

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

Flags controlling validation behavior

Implementations

impl ValidationFlags

pub const REPORT_WARNINGS: Self

Report warnings in addition to errors (default on).

pub const PROCESS_IDENTITY_CONSTRAINTS: Self

Process identity constraints (key, unique, keyref).

When this bit is clear, the runtime still parses xs:key / xs:unique / xs:keyref declarations but skips constraint evaluation during instance validation. Clear this bit to save work when you only need type-level validation.

pub const ALLOW_XML_ATTRIBUTES: Self

Accept every attribute in the reserved http://www.w3.org/XML/1998/namespace namespace (i.e. xml:lang, xml:space, xml:base, xml:id) without checking the element’s complex type for an allowing declaration or wildcard.

This bit is a lenient-parser convenience, not an XSD conformance mode. The XSD 1.0/1.1 spec requires every attribute — including those in the xml namespace — to be matched by a declared {attribute use} or an {attribute wildcard} whose namespace constraint admits the xml namespace. Enabling this flag therefore deviates from strict conformance; it is off by default.

Typical use: set this bit when feeding arbitrary XML through the validator and you want xml:lang to “just work” even against schemas that don’t explicitly import the xml namespace. Leave it clear for strict XSD conformance validation (including the W3C XSD test suite).

pub const STRICT_MODE: Self

Strict mode: treat all warnings as errors.

pub const PROCESS_ASSERTIONS: Self

Enable XSD 1.1 assertion processing (fragment buffering).

impl ValidationFlags

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u32) -> Option<Self>

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u32) -> Self

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u32) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

pub const fn intersects(&self, other: Self) -> bool

Whether any set bits in a source flags value are also set in a target flags value.

pub const fn contains(&self, other: Self) -> bool

Whether all set bits in a source flags value are also set in a target flags value.

pub fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

pub const fn intersection(self, other: Self) -> Self

The bitwise and (&) of the bits in two flags values.

pub const fn union(self, other: Self) -> Self

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl ValidationFlags

pub const fn iter(&self) -> Iter<ValidationFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<ValidationFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
