Struct DeployHeader

pub struct DeployHeader { /* private fields */ }

The header portion of a Deploy.

Implementations

impl DeployHeader

pub fn new( account: PublicKey, timestamp: Timestamp, ttl: TimeDiff, gas_price: u64, body_hash: Digest, dependencies: Vec<DeployHash>, chain_name: String, ) -> Self

Available on crate features std or json-schema only.

pub fn account(&self) -> &PublicKey

Returns the public key of the account providing the context in which to run the Deploy.

pub fn timestamp(&self) -> Timestamp

Returns the creation timestamp of the Deploy.

pub fn ttl(&self) -> TimeDiff

Returns the duration after the creation timestamp for which the Deploy will stay valid.

After this duration has ended, the Deploy will be considered expired.

pub fn expired(&self, current_instant: Timestamp) -> bool

Returns true if the Deploy has expired.

pub fn gas_price(&self) -> u64

Returns the sender’s gas price tolerance for block inclusion.

pub fn body_hash(&self) -> &Digest

Returns the hash of the body (i.e. the Wasm code) of the Deploy.

pub fn dependencies(&self) -> &Vec<DeployHash>

Returns the list of other Deploys that have to be executed before this one.

pub fn chain_name(&self) -> &str

Returns the name of the chain the Deploy should be executed on.

pub fn is_valid( &self, config: &TransactionConfig, timestamp_leeway: TimeDiff, at: Timestamp, deploy_hash: &DeployHash, ) -> Result<(), InvalidDeploy>

Available on crate feature std only.

Returns Ok if and only if the dependencies count and TTL are within limits, and the timestamp is not later than at + timestamp_leeway. Does NOT check for expiry.

pub fn expires(&self) -> Timestamp

Returns the timestamp of when the Deploy expires, i.e. self.timestamp + self.ttl.

Trait Implementations

impl Clone for DeployHeader

fn clone(&self) -> DeployHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for DeployHeader

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for DeployHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeployHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DeployHeader

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

Formats the value using the given formatter.

impl FromBytes for DeployHeader

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Hash for DeployHeader

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 JsonSchema for DeployHeader

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for DeployHeader

fn cmp(&self, other: &DeployHeader) -> 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 DeployHeader

fn eq(&self, other: &DeployHeader) -> 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 DeployHeader

fn partial_cmp(&self, other: &DeployHeader) -> 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 Serialize for DeployHeader

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToBytes for DeployHeader

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

where Self: Sized,

Consumes self and serializes to a Vec<u8>.
