Trait serde::de::EnumVisitor

pub trait EnumVisitor {
    type Error: Error;
    type Variant: VariantVisitor<Error=Self::Error>;
    fn visit_variant<V>(self) -> Result<(V, Self::Variant), Self::Error> where V: Deserialize;
}

EnumVisitor is a visitor that is created by the Deserializer and passed to the Deserialize in order to identify which variant of an enum to deserialize.

Associated Types

type Error: Error

The error type that can be returned if some error occurs during deserialization.

type Variant: VariantVisitor<Error=Self::Error>

The Visitor that will be used to deserialize the content of the enum variant.

Required Methods

fn visit_variant<V>(self) -> Result<(V, Self::Variant), Self::Error> where V: Deserialize

visit_variant is called to identify which variant to deserialize.
