Serializable version of StreamSpec without phantom types

Fields

state_name: String

program_id: Option<String>

Program ID (Solana address) - extracted from IDL

idl: Option<IdlSnapshot>

Embedded IDL for AST-only compilation

identity: IdentitySpec

handlers: Vec<SerializableHandlerSpec>

sections: Vec<EntitySection>

field_mappings: BTreeMap<String, FieldTypeInfo>

resolver_hooks: Vec<ResolverHook>

instruction_hooks: Vec<InstructionHook>

computed_fields: Vec<String>

Computed field paths (legacy, for backward compatibility)

computed_field_specs: Vec<ComputedFieldSpec>

Computed field specifications with full expression AST

content_hash: Option<String>

Deterministic content hash (SHA256 of canonical JSON, excluding this field) Used for deduplication and version tracking

views: Vec<ViewDef>

View definitions for derived/projected views

Implementations

impl SerializableStreamSpec

pub fn compute_content_hash(&self) -> String

Compute deterministic content hash (SHA256 of canonical JSON).

The hash is computed over the entire spec except the content_hash field itself, ensuring the same AST always produces the same hash regardless of when it was generated or by whom.

pub fn verify_content_hash(&self) -> bool

Verify that the content_hash matches the computed hash. Returns true if hash is valid or not set.

pub fn with_content_hash(self) -> SerializableStreamSpec

Set the content_hash field to the computed hash.

Trait Implementations

impl Clone for SerializableStreamSpec

fn clone(&self) -> SerializableStreamSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SerializableStreamSpec

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SerializableStreamSpec

fn deserialize<__D>( __deserializer: __D, ) -> Result<SerializableStreamSpec, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for SerializableStreamSpec

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
