Struct HeldItemData 

pub struct HeldItemData {
    pub player: String,
    pub off_hand: bool,
    pub key: String,
}

The bytes kept under key in the custom data of the stack player holds (off_hand: in its other hand): a saved item’s state.

Fields

player: String

off_hand: bool

key: String

Trait Implementations

impl Clone for HeldItemData

fn clone(&self) -> HeldItemData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeldItemData

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

Formats the value using the given formatter.

impl Fields for HeldItemData

const FIELDS: &'static [(&'static str, &'static str)]

Each field’s Rust name and the key it’s written as.

impl Schema for HeldItemData

fn encode(&self, __sd_w: &mut Writer)

Writes itself in the binary form, straight — Schema::write’s value encoded, unless the type knows better (derived ones do).

fn write_text(&self, __sd_w: &mut Writer)

Writes itself as text, straight (crate::text::Writer) — Schema::write’s value as text, unless the type knows better (derived ones do): no value tree is built on the way.

fn decode(__sd_d: &mut Decoder<'_>) -> Option<HeldItemData>

Reads itself from the binary form, straight; None when it isn’t what Schema::encode writes — then read_bytes reads the slow way, which says what’s wrong. Through a value unless the type knows better (derived ones do).

fn pack(&self, __sd_p: &mut Packer)

Packs itself into a frame (crate::frame): its binary form as bytes, unless the type packs itself (derived ones and plain types do).

fn unpack(__sd_u: &mut Unpacker<'_>) -> Option<HeldItemData>

Reads itself out of a frame; None if the bytes aren’t what Schema::pack writes.

fn shape() -> Shape

What the format looks like.

fn read(v: &ValueRef<'_>, cx: &mut Reader<'_>) -> Option<HeldItemData>

Reads v. Problems go to cx at its current path; None when the value couldn’t be read (the problem is in cx).

fn write(&self) -> Value

The value, as the format writes it.

fn absent() -> Option<Self>

The value of a field that isn’t there — None: the field is required.

fn skip(&self) -> bool

Whether a struct leaves this field out when writing it.

fn pack_list(items: &[Self], p: &mut Packer)

A list of these packed: a count, then each one (floats raw).

fn unpack_list(u: &mut Unpacker<'_>) -> Option<Vec<Self>>

A list of these out of a frame.

fn encode_list(items: &[Self], w: &mut Writer)

A list of these written straight (numbers pack theirs).

fn decode_list(d: &mut Decoder<'_>) -> Option<Vec<Self>>

A list of these read straight.

impl Service for HeldItemData

const ADDRESS: &'static str = ids::service_player::HELD_ITEM_DATA

Where it’s provided.

const KEY: Option<&'static str> = None

The field whose value picks the provider’s branch (block_id: each block answers its own), if it’s keyed — see crate::keyed.

type Reply = Option<Record>

What the provider answers.

fn key(&self) -> Option<&str>

The key field’s value, if it’s keyed.

fn address(&self) -> u32

Service::target’s number — the type’s own address cached.

fn target(&self) -> String

Where this call goes: the address, or its branch for the key.
