Struct Deserialized

pub struct Deserialized<T>(pub T);

Use it to parse T: Deserialize from Value.

#[derive(Deserialize)]
struct DeserializableStruct {
    // ...
}
// ...
let (Deserialized(val),): (Deserialized<DeserializableStruct>,)
    = from_row(row_with_single_json_column);

Trait Implementations

impl<T: Clone> Clone for Deserialized<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Deserialized<T>

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

Formats the value using the given formatter.

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

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: DeserializeOwned> From<ParseIr<Deserialized<T>>> for Deserialized<T>

fn from(value: ParseIr<Deserialized<T>>) -> Self

Converts to this type from the input type.

impl<T: DeserializeOwned> FromValue for Deserialized<T>

type Intermediate = ParseIr<Deserialized<T>>

fn from_value(v: Value) -> Self

Will panic if could not convert v to Self.

fn from_value_opt(v: Value) -> Result<Self, FromValueError>

Will return Err(Error::FromValueError(v)) if could not convert v to Self.

fn get_intermediate(v: Value) -> Result<Self::Intermediate, FromValueError>

Will return Err(Error::FromValueError(v)) if v is not convertible to Self.

impl<T: Hash> Hash for Deserialized<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: Ord> Ord for Deserialized<T>

fn cmp(&self, other: &Deserialized<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for Deserialized<T>

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<T: PartialOrd> PartialOrd for Deserialized<T>

fn partial_cmp(&self, other: &Deserialized<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T: Copy> Copy for Deserialized<T>

impl<T: Eq> Eq for Deserialized<T>

impl<T> StructuralPartialEq for Deserialized<T>
