Struct Impossible 

pub struct Impossible<Err>(/* private fields */);

Helper type for implementing a Serializer that does not support serializing one of the element types.

Trait Implementations

impl<Err> Serializer for Impossible<Err>

where Err: Error,

const FLAT_CLASSES: bool = false

Whether inner classes should be flattened.

type Error = Err

The error type.

type SerializeClass<'a> = Impossible<Err> where Self: 'a

Type returned from Serializer::serialize_class for class content serialization.

type SerializeField<'a> = Impossible<Err> where Self: 'a

Type returned from Serializer::serialize_field for field comment serialization.

type SerializeMethod<'a> = Impossible<Err> where Self: 'a

Type returned from Serializer::serialize_method for method arguments, variables and comment serialization.

type SerializeMethodArg<'a> = Impossible<Err> where Self: 'a

Type returned from Serializer::serialize_method_arg for method argument comment serialization.

type SerializeMethodVar<'a> = Impossible<Err> where Self: 'a

Type returned from Serializer::serialize_method_var for method variable comment serialization.

fn layout_matches<'de, D>() -> bool

where D: Deserializer<'de> + ?Sized,

Whether the deserializer’s class layout matches this serializer’s class layout.

fn serialize_comment(&mut self, _value: &str) -> Result<(), Self::Error>

Serializes a comment literal.

fn serialize_class<Dst>( &mut self, _src: &str, _dst: Dst, ) -> Result<Self::SerializeClass<'_>, Self::Error>

where Dst: IntoIterator<Item: AsRef<str>>,

Serializes a class.

where Dst: IntoIterator<Item: AsRef<str>>, DstDesc: IntoIterator<Item: AsRef<str>>,

Serializes a field.

fn serialize_method<Dst, DstDesc>( &mut self, _src: &str, _desc: Option<&str>, _dst: Dst, _dst_desc: Option<DstDesc>, ) -> Result<Self::SerializeMethod<'_>, Self::Error>

where Dst: IntoIterator<Item: AsRef<str>>, DstDesc: IntoIterator<Item: AsRef<str>>,

Serializes a method.

fn serialize_method_arg<Dst>( &mut self, _src: Option<&str>, _dst: Option<Dst>, _pos: Option<usize>, _lv_index: Option<usize>, ) -> Result<Self::SerializeMethodArg<'_>, Self::Error>

where Dst: IntoIterator<Item: AsRef<str>>,

Serializes a method argument.

fn serialize_method_var<Dst>( &mut self, _src: Option<&str>, _dst: Option<Dst>, _lv_index: Option<usize>, _lvt_row_index: Option<usize>, _op_idx: Option<(usize, Option<usize>)>, ) -> Result<Self::SerializeMethodVar<'_>, Self::Error>

where Dst: IntoIterator<Item: AsRef<str>>,
