Struct schema_analysis::Field

source ·
pub struct Field {
    pub status: FieldStatus,
    pub schema: Option<Schema>,
}
Expand description

A Field is a useful abstraction to record metadata that does not belong or would be unyieldy to place into the Schema and to account for cases in which the existence of a Field might be known, but nothing is known about its shape.

Fields§

§status: FieldStatus

The status holds information on the the field, like whether it might be null or missing altogether. Duplicate fields are also recorded.

§schema: Option<Schema>

The inner Schema is optional because we might have no information on the shape of the field (like for an empty array).

Implementations§

Returns a Field with the given Schema and default FieldStatus.

Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Merge other into self.
Formats the value using the given formatter. Read more
Returns the “default value” for a type. Read more
Deserialize this value from the given Serde deserializer. Read more
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Serialize this value into the given Serde serializer. Read more
Returns true if self and other share the same structure.
Returns true if self and other DO NOT share the same structure.

Auto Trait Implementations§

Blanket Implementations§

Gets the TypeId of self. Read more
Immutably borrows from an owned value. Read more
Mutably borrows from an owned value. Read more
Merge other into self. Trait object is returned if merging was unsuccessful.
Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Creates owned data from borrowed data, usually by cloning. Read more
Uses borrowed data to replace owned data, usually by cloning. Read more
The type returned in the event of a conversion error.
Performs the conversion.
