Require the Decoder
to figure out how to drive the visitor based
on what data type is in the input.
When implementing FromStream
, you should avoid relying on
Decoder::decode_any
unless you need to be told by the
Decoder what type is in the input. Know that relying on
Decoder::decode_any
means your data type will be able to
decode self-describing formats only.

Hint that the FromStream
type is expecting an array of f64
s.

Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting a map of key-value pairs.
sourcefn decode_option<'life0, 'async_trait, V>(
&'life0 mut self,

) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where

) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting an optional value.
This allows decoders that encode an optional value as a nullable
value to convert the null value into None
and a regular value into
Some(value)
.
sourcefn decode_seq<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where

) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting a sequence of values.
sourcefn decode_string<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where

V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting a string value.
sourcefn decode_tuple<'life0, 'async_trait, V>(
&'life0 mut self,
len: usize,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where

fn decode_tuple<'life0, 'async_trait, V>(
&'life0 mut self,
len: usize,

) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting a sequence of values and
knows how many values there are without looking at the encoded data.
sourcefn decode_unit<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,

fn decode_unit<'life0, 'async_trait, V>(

) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting a unit value (i.e. ()
).
sourcefn decode_uuid<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
fn decode_uuid<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type is expecting a uuid::Uuid
.
sourcefn decode_ignored_any<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
fn decode_ignored_any<'life0, 'async_trait, V>(
&'life0 mut self,
visitor: V
) -> Pin<Box<dyn Future<Output = Result<V::Value, Self::Error>> + Send + 'async_trait>>where
V: 'async_trait + Visitor,
Self: 'async_trait,
'life0: 'async_trait,
Hint that the FromStream
type needs to decode a value whose type
doesn’t matter because it is ignored.
Decoders for non-self-describing formats may not support this mode.
