Enum DataLoss 

pub enum DataLoss {
    None,
    TopLevel,
    Nested,
}

Whether an encoder is allowed to drop input keys, and where.

Variants

None

Encoder must preserve every input key (top-level and nested). Failing this is a bug.

TopLevel

Encoder may drop the wrapping object’s top-level keys (sibling fields of the chosen array). It must still preserve all keys inside the array elements.

Nested

Encoder may drop nested-object keys inside array elements (e.g. older naive CSV that only kept primitive columns).

Trait Implementations

impl Clone for DataLoss

fn clone(&self) -> DataLoss

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataLoss

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

Formats the value using the given formatter.

impl PartialEq for DataLoss

fn eq(&self, other: &DataLoss) -> 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.
