Fields§

§default: Option<String>

Optional path to a function that will produce the default value in case the field is omitted from the serialized representation.

See also: https://serde.rs/field-attrs.html#default--path

An empty string may be used as value, in which case Default::default is assumed. See also: https://serde.rs/field-attrs.html#default

§deserialize_with: Option<String>

Optional Serde dependency used for deserialization.

See: https://serde.rs/field-attrs.html#deserialize_with

§flatten: bool

Determines whether the field should be flattened into the parent struct.

See: https://serde.rs/attr-flatten.html

§rename: Option<String>

Optional name to use in the serialized format (only used if different than the field name itself).

See also: https://serde.rs/field-attrs.html#rename

§serialize_with: Option<String>

Optional Serde dependency used for serialization.

See also: https://serde.rs/field-attrs.html#serialize_with

§skip_serializing_if: Option<String>

Optional path to a function to determine whether serialized should be skipped for a particular value.

E.g.: can be used to omit Options by specifying skip_serializing_if = "Option::is_none".

See also: https://serde.rs/field-attrs.html#skip_serializing_if
