Implementations

impl Slot

pub const fn new(slot: [u8; 32]) -> Self

Creates a new slot from a 32-byte array.

pub fn from_label(label: &str) -> Self

Creates a slot from a string label.

pub fn derived(namespace: &[u8; 32], parts: &[&[u8]]) -> Self

Creates a derived slot from a namespace and parts.

pub fn read(self) -> Result<[u8; 32]>

Reads the raw 32-byte value from this slot.

pub fn write(self, value: &[u8; 32]) -> Result<()>

Writes a raw 32-byte value to this slot.

pub fn write_typed<T: Codec32>(self, value: &T) -> Result<()>

Writes a typed value implementing Codec32.

pub fn read_typed<T: Codec32>(self) -> Result<T>

Reads a typed value implementing Codec32.

pub fn write_u64(self, value: u64) -> Result<()>

Writes a u64 value (little-endian).

pub fn read_u64(self) -> Result<u64>

Reads a u64 value (little-endian).

pub fn write_u128(self, value: u128) -> Result<()>

Writes a u128 value (little-endian).

pub fn read_u128(self) -> Result<u128>

Reads a u128 value (little-endian).

Trait Implementations

impl Clone for Slot

fn clone(&self) -> Slot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Slot

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

Formats the value using the given formatter.

impl Hash for Slot

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 PartialEq for Slot

fn eq(&self, other: &Slot) -> 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.
