Struct casper_node::types::Deploy

pub struct Deploy { /* fields omitted */ }

A deploy; an item containing a smart contract along with the requester's signature(s).

Implementations

impl Deploy

pub fn new(
    timestamp: Timestamp,
    ttl: TimeDiff,
    gas_price: u64,
    dependencies: Vec<DeployHash>,
    chain_name: String,
    payment: ExecutableDeployItem,
    session: ExecutableDeployItem,
    secret_key: &SecretKey,
    rng: &mut NodeRng
) -> Deploy

Constructs a new signed Deploy.

pub fn sign(&mut self, secret_key: &SecretKey, rng: &mut NodeRng)

Adds a signature of this deploy's hash to its approvals.

pub fn id(&self) -> &DeployHash

Returns the DeployHash identifying this Deploy.

pub fn header(&self) -> &DeployHeader

Returns a reference to the DeployHeader of this Deploy.

pub fn take_header(self) -> DeployHeader

Returns the DeployHeader of this Deploy.

pub fn payment(&self) -> &ExecutableDeployItem

Returns the ExecutableDeployItem for payment code.

pub fn session(&self) -> &ExecutableDeployItem

Returns the ExecutableDeployItem for session code.

pub fn approvals(&self) -> &[Approval]

Returns the Approvals for this deploy.

pub fn deploy_type(&self) -> Result<DeployType, Error>

Returns the DeployType.

pub fn is_valid(&mut self) -> bool

Returns true if and only if:

• the deploy hash is correct (should be the hash of the header), and
• the body hash is correct (should be the hash of the body), and
• all approvals are valid signatures of the deploy hash

Note: this is a relatively expensive operation, requiring re-serialization of the deploy, hashing, and signature checking, so should be called as infrequently as possible.

pub fn is_acceptable(
    &mut self,
    chain_name: String,
    config: DeployConfig
) -> bool

Returns true if and only if:

• the chain_name is correct,
• the configured parameters are complied with,
• the deploy is valid

Note: if everything else checks out, calls the computationally expensive is_valid method.

Trait Implementations

impl Clone for Deploy

pub fn clone(&self) -> Deploy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for Deploy

pub const IS_DYNAMIC: bool

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

pub const STATIC_HEAP_SIZE: usize

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.

pub fn estimate_heap_size(&self) -> usize

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

impl Debug for Deploy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Deploy

pub fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Deploy

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

Formats the value using the given formatter.

impl DocExample for Deploy

pub fn doc_example() -> &'static Self

Generates a hardcoded example of Self.

impl Eq for Deploy

impl FromBytes for Deploy

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

Deserializes the slice into Self.

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

Deserializes the Vec<u8> into Self.

impl Hash for Deploy

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Item for Deploy

type Id = DeployHash

The type of ID of the item.

pub const TAG: Tag

The tag representing the type of the item.

pub const ID_IS_COMPLETE_ITEM: bool

Whether the item's ID is the complete item or not.

pub fn id(&self) -> Self::Id

The ID of the specific item.

impl JsonSchema for Deploy

pub fn schema_name() -> String

The name of the generated JSON Schema.

pub fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

pub fn is_referenceable() -> bool

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

impl Ord for Deploy

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Deploy> for Deploy

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

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

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

This method tests for !=.

impl PartialOrd<Deploy> for Deploy

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

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

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

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

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

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

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

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

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

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

impl Serialize for Deploy

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

Serialize this value into the given Serde serializer.

impl StructuralEq for Deploy

impl StructuralPartialEq for Deploy

impl ToBytes for Deploy

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

Serializes &self to a Vec<u8>.

pub 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.

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

Consumes self and serializes to a Vec<u8>.
