Struct seredies::components::RedisString

#[repr(transparent)]
pub struct RedisString<T: ?Sized>(pub T);

Adapter type that serializes the contained value as a string.

Frequently, especially when sending commands, Redis will require data to be passed as a string, even when the underlying data is something like an integer. This type serializes its inner value as a string, and works on most primitive types. This will serialize unit enum variants and unit structs as their name.

Note that this type cannot distinguish a [u8] from other kinds of slices; be sure to use a container like serde_bytes::Bytes to ensure that these slices are serialized as bytes objects rather than sequences.

Example

use seredies::components::RedisString;
use serde::{Serialize, Deserialize};
use serde_test::{assert_tokens, assert_ser_tokens, Token};

assert_tokens(&RedisString("Hello"), &[Token::BorrowedStr("Hello")]);
assert_tokens(&RedisString(5i32), &[Token::Str("5")]);
assert_tokens(&RedisString(4.5), &[Token::Str("4.5")]);

let s: &RedisString<str> = RedisString::new_ref("string");
assert_tokens(&s, &[Token::BorrowedStr("string")]);

#[derive(Serialize, Deserialize, Debug, PartialEq, Eq)]
struct UnitStruct;

#[derive(Serialize, Deserialize, Debug, PartialEq, Eq)]
enum Data {
    Foo,
    Bar
}

assert_tokens(&RedisString(UnitStruct), &[Token::Str("UnitStruct")]);
assert_tokens(&RedisString(Data::Bar), &[Token::Str("Bar")]);

Implementations

impl<T: ?Sized> RedisString<T>

pub fn new_ref(value: &T) -> &Self

Convert a reference to some underlying type into a reference to a RedisString containing that object. This works even on unsized values and allows for the creation of things like &RedisString<str>.

Trait Implementations

impl<T: Clone + ?Sized> Clone for RedisString<T>

fn clone(&self) -> RedisString<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + ?Sized> Debug for RedisString<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default + ?Sized> Default for RedisString<T>

fn default() -> RedisString<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for &'de RedisString<T>where &'de T: Deserialize<'de>, T: ?Sized + 'de,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'de, T> Deserialize<'de> for RedisString<T>where T: Deserialize<'de> + ?Sized,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq + ?Sized> PartialEq<RedisString<T>> for RedisString<T>

fn eq(&self, other: &RedisString<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for RedisString<T>where T: Serialize + ?Sized,

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Copy + ?Sized> Copy for RedisString<T>

impl<T: Eq + ?Sized> Eq for RedisString<T>

impl<T: ?Sized> StructuralEq for RedisString<T>
