Struct Field 

pub struct Field {
    pub status: FieldStatus,
    pub schema: Option<Schema>,
}

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

impl Field

pub fn with_schema(schema: Schema) -> Self

Returns a Field with the given Schema and default FieldStatus.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Coalesce for Field

fn coalesce(&mut self, other: Self)

where Self: Sized,

Merge other into self.

impl Debug for Field

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

Formats the value using the given formatter.

impl Default for Field

fn default() -> Field

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Field

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Field

fn eq(&self, other: &Field) -> 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 Serialize for Field

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralEq for Field

fn structural_eq(&self, other: &Self) -> bool

Returns true if self and other share the same structure.

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

Returns true if self and other DO NOT share the same structure.
