Struct Schema 

pub struct Schema {
    pub name: String,
    pub version: u32,
    pub chains: Vec<String>,
    pub address: Option<Vec<String>>,
    pub event: String,
    pub fingerprint: EventFingerprint,
    pub supersedes: Option<String>,
    pub superseded_by: Option<String>,
    pub deprecated: bool,
    pub fields: Vec<(String, FieldDef)>,
    pub meta: SchemaMeta,
}

A parsed, validated schema definition. This is the in-memory representation of a CSDL file.

Fields

name: String

PascalCase schema name, e.g. “UniswapV3Swap”

version: u32

Schema version (increments on breaking changes)

chains: Vec<String>

Chains this schema applies to (by slug)

address: Option<Vec<String>>

Contract address(es) — None means “any address”

event: String

The blockchain event name, e.g. “Swap”

fingerprint: EventFingerprint

Fingerprint: keccak256 of the event signature (EVM) or SHA-256 (non-EVM)

supersedes: Option<String>

Optional: the schema this one supersedes

superseded_by: Option<String>

Optional: forward pointer to a successor schema

deprecated: bool

Whether this schema is deprecated

fields: Vec<(String, FieldDef)>

Ordered field definitions (order matters for ABI decode)

meta: SchemaMeta

Metadata

Implementations

impl Schema

pub fn fields_map(&self) -> HashMap<&str, &FieldDef>

Returns field definitions as a lookup map (name → def).

pub fn indexed_fields(&self) -> Vec<(&str, &FieldDef)>

Returns only the indexed fields (EVM topics[1..]).

pub fn data_fields(&self) -> Vec<(&str, &FieldDef)>

Returns only the non-indexed fields (EVM data payload).

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Schema

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Schema

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
