Enum VersionSource

#[repr(u8)]
pub enum VersionSource {
    Stored(Base64VecU8),
    PublishGlobal(Base64VecU8),
    ExistingGlobal(Base58CryptoHash),
}

Where a version’s code comes from, as one value.

Supersedes the (DeployMode, Vec<u8>) pair, which admitted a combination that means nothing: Normal alongside bytes already published as a global contract. Modelled on crate::upgrade::UpgradeSource, which draws the same distinction for the upgrade path.

Borsh tags are pinned via explicit discriminants (use_discriminant): tmplrmgr plan files persist these args as opaque borsh, so the tag must not track declaration order. Discriminants 0 and 1 match DeployMode::Normal/GlobalHash, and [Base64VecU8] is a transparent borsh newtype over Vec<u8> — so (version_key, Stored(code)) is byte-identical to the older (version_key, DeployMode::Normal, code). borsh_is_wire_compatible_with_deploy_mode pins this.

Variants

Stored(Base64VecU8)

WASM held in registry state; deploy copies it onto each account.

PublishGlobal(Base64VecU8)

WASM published as a new global contract; the registry keeps only the hash.

ExistingGlobal(Base58CryptoHash)

A global contract already on chain, by code hash. No publish cost.

Trait Implementations

impl BorshDeserialize for VersionSource

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSchema for VersionSource

fn declaration() -> Declaration

Get the name of the type without brackets.

fn add_definitions_recursively( definitions: &mut BTreeMap<Declaration, Definition>, )

Recursively, using DFS, add type definitions required for this type. Type definition partially explains how to serialize/deserialize a type.

impl BorshSerialize for VersionSource

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for VersionSource

fn clone(&self) -> VersionSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VersionSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VersionSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EnumExt for VersionSource

fn deserialize_variant<__R: Read>( reader: &mut __R, variant_tag: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

impl JsonSchema for VersionSource

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 PartialEq for VersionSource

fn eq(&self, other: &VersionSource) -> 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 Serialize for VersionSource

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for VersionSource

impl StructuralPartialEq for VersionSource
