Struct DecodeSlot 

pub struct DecodeSlot<T> { /* private fields */ }

Available on crate feature serde only.

Re-export of the nextjson format-neutral contracts used by tzcraft.

Available as tzcraft::codec::NsonSerialize and friends so downstream code can write tzcraft::codec::nextencode(...) without naming nextjson directly. Safe caller-provided storage used by NsonDeserialize::nextdecode_into.

The value starts uninitialized, but unlike a public MaybeUninit<T> contract it cannot be read before a successful write. Incorrect third-party implementations therefore cannot cause undefined behavior in safe code.

Implementations

impl<T> DecodeSlot<T>

pub const fn new() -> DecodeSlot<T>

Create an empty nextdecode slot.

pub fn write(&mut self, value: T)

Replace the slot contents with a fully initialized value.

pub fn take(&mut self) -> Option<T>

Remove and return the initialized value, if present.

pub fn is_initialized(&self) -> bool

Return whether the slot currently contains a value.

Trait Implementations

fn default() -> DecodeSlot<T>

Returns the “default value” for a type.
