Struct JsonFormatAdapter 

pub struct JsonFormatAdapter { /* private fields */ }

A FormatAdapter that parses a JSON array of objects.

Entities and edges may be mixed in the same array — the adapter dispatches by checking for source + target keys (edge) vs. their absence (entity).

Construct with JsonFormatAdapter::new, passing the raw JSON bytes. The constructor parses eagerly; iteration is cheap once constructed.

Implementations

impl JsonFormatAdapter

pub fn new(json_input: &str) -> Result<Self, AdapterError>

Parse json_input and return a ready adapter.

Returns Err(AdapterError::Parse) if json_input is not valid JSON or is not a JSON array at the top level.

Trait Implementations

impl FormatAdapter for JsonFormatAdapter

fn name(&self) -> &str

Short name of the format handled by this adapter (e.g. "csv", "json").

fn entities( &mut self, ) -> impl Iterator<Item = Result<EntityRecord, AdapterError>>

Iterate over entity records in the source.

fn edges(&mut self) -> impl Iterator<Item = Result<EdgeRecord, AdapterError>>

Iterate over edge records in the source.

fn warnings(&self) -> &[String]

Non-fatal warnings accumulated during parsing (e.g. unknown columns, missing optional fields).
