Trait InputNode 

pub trait InputNode {
    // Required methods
    fn type_to_node() -> Node;
    fn data_to_node(&self) -> Node;
    fn oneof_variant(&self) -> Option<&'static str>;
    fn parse_unknown(&self, context: &mut Context<'_>) -> bool;
}

Trait for all Rust types that represent input tree node types.

Required Methods

fn type_to_node() -> Node

Creates an empty output node for a protobuf datum of this type.

For primitive types, this fills the value with protobuf’s default.

fn data_to_node(&self) -> Node

Creates an empty output node for a protobuf datum with this value.

fn oneof_variant(&self) -> Option<&'static str>

Returns the name of the selected variant of a oneof field, if this is a rust enum used to represent a oneof field.

fn parse_unknown(&self, context: &mut Context<'_>) -> bool

Complete the subtrees of this datum in output that have not already been parsed using UnknownField nodes. Returns whether any such nodes were added.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

impl<T: ProtoPrimitive> InputNode for T

Blanket implementation to make all protobuf primitives behave like generic protobuf datums.

Note: if Rust would allow it, we could define blanket implementations for ProtoMessage and ProtoOneOf as well, since they’re always the same. Unfortunately, we can only define a single blanket implementation, so we opt for the one that isn’t already generated via derive macros.
