Struct schema_analysis::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 copy 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,
