Struct mysql_async::Unserialized

pub struct Unserialized<T>(pub T);

Use it to parse T: Decodable from Value.

#[derive(RustcDecodable)]
struct DecodableStruct {
    // ...
}
// ...
let (Unserialized(val),): (Unserialized<DecodableStruct>,)
    = from_row(row_with_single_json_column);

Trait Implementations

impl<T: Clone> Clone for Unserialized<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Copy> Copy for Unserialized<T>

impl<T: PartialEq> PartialEq for Unserialized<T>

fn eq(&self, __arg_0: &Unserialized<T>) -> bool

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

fn ne(&self, __arg_0: &Unserialized<T>) -> bool

This method tests for !=.

impl<T: PartialOrd> PartialOrd for Unserialized<T>

fn partial_cmp(&self, __arg_0: &Unserialized<T>) -> Option<Ordering>

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

fn lt(&self, __arg_0: &Unserialized<T>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &Unserialized<T>) -> bool

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

fn gt(&self, __arg_0: &Unserialized<T>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &Unserialized<T>) -> bool

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

impl<T: Eq> Eq for Unserialized<T>

impl<T: Ord> Ord for Unserialized<T>

fn cmp(&self, __arg_0: &Unserialized<T>) -> Ordering

This method returns an Ordering between self and other.

impl<T: Debug> Debug for Unserialized<T>

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

Formats the value using the given formatter.

impl<T: Hash> Hash for Unserialized<T>

fn hash<__HT: Hasher>(&self, __arg_0: &mut __HT)

Feeds this value into the state given, updating the hasher as necessary.

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

Feeds a slice of this type into the state provided.

impl<T: Decodable> FromValue for Unserialized<T>

type Intermediate = UnserializedIr<T>

fn from_value(v: Value) -> Self

Will panic if could not convert v to Self.

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

Will return Err(ErrorKind::FromValue(v).into()) if could not convert v to Self.

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

Will return Err(ErrorKind::FromValue(v).into()) if v is not convertible to Self.
