Struct DisplayFromStr 

pub struct DisplayFromStr;

Serializes with Display and deserializes with FromStr.

The value is represented as a string. Only strings are accepted when deserializing.

use std::net::IpAddr;
use deser::{Deserialize, Serialize};
use deser::adapters::DisplayFromStr;

#[derive(Serialize, Deserialize)]
pub struct Server {
    #[deser(as = DisplayFromStr)]
    addr: IpAddr,

Trait Implementations

impl<'de, T> Deserialize<'de, T> for DisplayFromStr

where T: FromStr + Send, T::Err: Display,

fn deserialize_atom( slot: &mut Slot<T, Self>, atom: Atom<'_>, state: &mut State, ) -> Result<(), Error>

Deserializes an atom into the slot.

fn expecting() -> Cow<'static, str>

Returns what the value expects, for error messages.

fn deserialize_into<'out>( out: &'out mut Option<T>, state: &mut State, ) -> SinkHandle<'out, 'de>

Creates a sink that deserializes the value into the given slot.

fn deserialize_borrowed_atom( slot: &mut Slot<T, Self>, atom: Atom<'de>, state: &mut State, ) -> Result<(), Error>

Deserializes an atom that borrows from the data being deserialized into the slot.

fn describe_type(d: &mut dyn Describe)

Describes the Rust shape of the type.

fn initial_value() -> Option<T>

Provides the value of a missing struct field.

fn deserialize_update<'out>( value: &'out mut T, state: &mut State, ) -> SinkHandle<'out, 'de>

Creates a sink that updates an existing value.

impl<T: Display + ?Sized> Serialize<T> for DisplayFromStr

fn serialize<'a>(value: &'a T, _state: &mut State) -> Result<Emit<'a>, Error>

Serializes the value.

fn finish(value: &T, state: &mut State) -> Result<(), Error>

Invoked after the serialization finished.

fn is_optional(value: &T) -> bool

Checks if the value represents an optional value.

fn describe(value: &T, d: &mut dyn Describe)

Describes the Rust shape of the value.

fn container_shape(value: &T) -> ContainerShape

Returns the shape of the value if it’s a map or sequence.
