Struct ElementDecl 

pub struct ElementDecl {
    pub name: QName,
    pub type_def: TypeRef,
    pub nillable: bool,
    pub default: Option<String>,
    pub fixed: Option<String>,

}

<xs:element> declaration — top-level or local.

Fields

name: QName

type_def: TypeRef

Resolved type — may be a simple or complex type. Anonymous inline types end up here too.

nillable: bool

xs:nillable attribute. xsi:nil="true" instances on this element are valid only when this is true.

default: Option<String>

default="…" value applied when the element is empty.

fixed: Option<String>

fixed="…" value the element must match if present.

abstract_: bool

abstract="true" — element cannot appear in instances; only substitutes for it can.

substitution_group: Option<QName>

Head of substitution group this element substitutes into, resolved by the schema compiler.

block: BlockSet

block="restriction|extension|substitution" — disallowed derivation modes for substitutes. Stored as a flag set.

final_: BlockSet

final="restriction|extension" — derivation forms that must not derive from this element.

identity: Vec<IdentityConstraint>

<xs:key> / <xs:keyref> / <xs:unique> constraints declared directly on this element. Empty for the common case. Each constraint scopes to the subtree rooted at this element.

Trait Implementations

impl Debug for ElementDecl

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

Formats the value using the given formatter.
