Struct CodeId

pub struct CodeId(/* private fields */);

Code identifier.

This identifier can be obtained as a result of executing the gear.uploadCode extrinsic. Actually, the code identifier is the Blake2 hash of the Wasm binary code blob.

Code identifier is required when creating programs from programs (see gstd::prog module for details).

Implementations

impl CodeId

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

Creates a new CodeId from a 32-byte array.

impl CodeId

pub const fn zero() -> Self

Creates a new zero CodeId.

pub fn is_zero(&self) -> bool

Checks whether CodeId is zero.

impl CodeId

pub fn into_bytes(self) -> [u8; 32]

Returns CodeIdas bytes array.

Trait Implementations

impl<__AsMutT: ?Sized> AsMut<__AsMutT> for CodeId

where [u8; 32]: AsMut<__AsMutT>,

fn as_mut(&mut self) -> &mut __AsMutT

impl<__AsRefT: ?Sized> AsRef<__AsRefT> for CodeId

where [u8; 32]: AsRef<__AsRefT>,

fn as_ref(&self) -> &__AsRefT

impl Clone for CodeId

fn clone(&self) -> CodeId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CodeId

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

Formats the value using the given formatter.

impl Default for CodeId

fn default() -> CodeId

Returns the “default value” for a type.

impl Display for CodeId

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

Formats the value using the given formatter.

impl From<[u8; 32]> for CodeId

fn from(original: [u8; 32]) -> CodeId

Converts to this type from the input type.

impl From<CodeId> for [u8; 32]

fn from(original: CodeId) -> Self

Converts to this type from the input type.

impl From<CodeId> for H256

fn from(value: CodeId) -> Self

Converts to this type from the input type.

impl From<H256> for CodeId

fn from(h256: H256) -> Self

Converts to this type from the input type.

impl From<u64> for CodeId

fn from(value: u64) -> Self

Converts to this type from the input type.

impl FromStr for CodeId

type Err = ConversionError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CodeId

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 Ord for CodeId

fn cmp(&self, other: &CodeId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CodeId

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

impl PartialOrd for CodeId

fn partial_cmp(&self, other: &CodeId) -> Option<Ordering>

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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

impl TryFrom<&[u8]> for CodeId

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
