Struct ArrowEventSchema 

pub struct ArrowEventSchema {
    pub full_name: String,
    pub payload_column: String,
    pub fields: Vec<ArrowField>,
    pub schema_hash: u64,
}

One per-event payload struct. Combined into the unified obs_events table by ArrowSchemaModel.

Fields

full_name: String

Stable identity, matches EventSchema::FULL_NAME.

payload_column: String

payload_<full_name_snake> — the column name for this event’s per-event Nested struct. Spec 22 § 1.1.

fields: Vec<ArrowField>

One Arrow field per declared schema field.

schema_hash: u64

First 8 bytes of BLAKE3 over the canonical descriptor.

Implementations

impl ArrowEventSchema

pub fn from_erased(schema: &dyn EventSchemaErased) -> Self

Build an ArrowEventSchema from an EventSchemaErased view. The leaf-type inference uses FieldRole plus a small heuristic on the field name suffix (*_ns, *_ms, *_count, *_id). Codegen will eventually own the type table directly; this keeps Phase-4 sinks operational against the Phase-1/2 codegen.

Trait Implementations

impl Clone for ArrowEventSchema

fn clone(&self) -> ArrowEventSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArrowEventSchema

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

Formats the value using the given formatter.
