Struct gstd::CodeId

pub struct CodeId(_);

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 prog module for details).

Implementations

impl CodeId

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

Create a new CodeId from a 32-byte array.

pub fn from_slice(slice: &[u8]) -> Result<Self>

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<[u8; 32]> for CodeId

fn from(arr: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<CodeId> for [u8; 32]

fn from(other: CodeId) -> Self

Converts to this type from the input type.

impl From<CodeId> for CodeId

fn from(other: CodeId) -> Self

Converts to this type from the input type.

impl From<CodeId> for CodeId

fn from(other: 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 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,

impl Ord for CodeId

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<CodeId> for CodeId

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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