Struct HexForm

pub struct HexForm<T>(/* private fields */);

A dummy container for use inside #[serde(with)] attribute if the underlying type implements Hex.

Why a separate container?

We need a separate type (instead of just using impl<T> Hex<T> for T) both for code clarity and because otherwise invocations within generated serde code would be ambiguous for types implementing Serialize / Deserialize.

Trait Implementations

impl<T: Debug> Debug for HexForm<T>

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

Formats the value using the given formatter.

impl<T, E> Hex<T> for HexForm<T>

where T: AsRef<[u8]> + for<'a> TryFrom<&'a [u8], Error = E>, E: Display,

type Error = E

Available on crate feature alloc only.

Error returned on unsuccessful deserialization.

fn create_bytes(buffer: &T) -> Cow<'_, [u8]>

Available on crate feature alloc only.

Converts the value into bytes. This is used for serialization.

fn from_bytes(bytes: &[u8]) -> Result<T, Self::Error>

Available on crate feature alloc only.

Creates a value from the byte slice.

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

Available on crate feature alloc only.

Serializes the value for serde. This method is not meant to be overridden.

fn deserialize<'de, D>(deserializer: D) -> Result<T, D::Error>

where D: Deserializer<'de>,

Available on crate feature alloc only.

Deserializes a value using serde. This method is not meant to be overridden.
