Struct Serializer2D 

pub struct Serializer2D<'a> { /* private fields */ }

Builder for Index2D serialization, created by Index2D::serialize.

Set optional per-item payloads, the streaming-tuned interleaved layout, and descriptive metadata (CRS / content type / attribution), then call to_bytes or to_bytes_into. The metadata strings are stored opaquely and read back with read_metadata.

Implementations

impl<'a> Serializer2D<'a>

pub fn payloads<P: AsRef<[u8]>>(self, payloads: &'a [P]) -> Self

Attach one opaque payload blob per item, in item order.

pub fn records(self, stride: usize, flat: &'a [u8]) -> Self

Attach a fixed-width payload: flat is the concatenation of one stride-byte record per item, in item order (item i is flat[i * stride ..][.. stride]). Because every record is the same size, the offset table is dropped (the reader addresses record r by arithmetic), which shrinks the file and lets a view borrow the records as a zero-copy typed slice. flat.len() must be num_items * stride.

pub fn triangles<T: Triangle2>(self, triangles: &'a [T]) -> Self

Attach a fixed-width triangle payload (T = Triangle2D for f64 or Triangle2DF32 for f32): one triangle per item, in item order. A convenience over records; pair it with Index2D::from_triangles.

pub fn interleaved(self) -> Self

Available on crate feature stream only.

Use the streaming-tuned interleaved node layout (see Index2D::to_bytes_interleaved).

pub fn crs(self, crs: &'a str) -> Self

Set the coordinate reference system identifier (opaque, e.g. "EPSG:4326").

pub fn content_type(self, content_type: &'a str) -> Self

Set the payload content type / media type (e.g. "application/geo+json").

pub fn attribution(self, attribution: &'a str) -> Self

Set an attribution / license string.

pub fn to_bytes(self) -> Result<Vec<u8>, PayloadError>

Serialize into a new buffer.

pub fn to_bytes_into(self, out: &mut Vec<u8>) -> Result<(), PayloadError>

Serialize into a reused buffer (cleared first).
