Struct serde_redis::decode::Deserializer

pub struct Deserializer { /* fields omitted */ }

deserializes Redis Values

Deserializes a sequence of redis values. In the case of a Bulk value (eg, a nested list), another deserializer is created for that sequence. The limit to nested sequences is proportional to the maximum stack depth in current machine.

If creating a Deserializer manually (ie not using from_redis_value()), the redis values must first be placed in a Vec.

Methods

impl Deserializer

fn new<V>(values: V) -> Deserializer where V: IntoValueVec

fn peek(&mut self) -> Option<&Value>

Returns a reference to the next value

fn next(&mut self) -> Result<Value>

Return the next value

fn next_bulk(&mut self) -> Result<Vec<Value>>

fn read_string(&mut self) -> Result<String>

Trait Implementations

impl Debug for Deserializer

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Deserializer for Deserializer

type Error = Error

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

Hint that the Deserialize type is expecting a f64 value.

fn deserialize_str<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a string value and does not benefit from taking ownership of buffered data owned by the Deserializer.

fn deserialize_char<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a char value.

fn deserialize_bool<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

fn deserialize_bytes<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a byte array and does not benefit from taking ownership of buffered data owned by the Deserializer.

fn deserialize_byte_buf<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a byte array and would benefit from taking ownership of buffered data owned by the Deserializer.

fn deserialize_tuple_struct<V>(self,
                               _name: &'static str,
                               len: usize,
                               visitor: V)
                               -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a tuple struct with a particular name and number of fields.

fn deserialize_tuple<V>(self, _len: usize, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a tuple value with a particular number of elements.

fn deserialize_seq<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a sequence of values.

fn deserialize_seq_fixed_size<V>(self,
                                 _len: usize,
                                 visitor: V)
                                 -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a sequence of values and knows how many values there are without looking at the serialized data.

fn deserialize_map<V>(self, visitor: V) -> Result<V::Value> where V: Visitor

Hint that the Deserialize type is expecting a map of key-value pairs.
