Trait Point

pub trait Point: Debug {
    // Required methods
    fn as_fields(&self) -> &dyn PFields;
    fn hash_ref(&self) -> &B64<[u8; 32]>;
    fn xheader_ref(&self) -> &XHeader;

}

A trait to access fields of a point. Auto impls PointExt, PFields, and PFieldsExt.

A Point is the combination of Point, LkHash, XHeader. the trait is impl for various layouts such as PointBox, PointArc.

There are wrapping structs in as [reroute] that provide extended options.

Required Methods

fn as_fields(&self) -> &dyn PFields

fn hash_ref(&self) -> &B64<[u8; 32]>

fn xheader_ref(&self) -> &XHeader

fn recv(&self) -> Option<U64>

recv is a special field. It depends on the context. Reading directly from the database it should return the stamp at which it was inserted. NOTE: Do not rely on this value being unique - in the db or otherwise.

fn byte_segments(&self) -> ByteSegments<'_>

Provided Methods

fn as_box(&self) -> PointBox

fn as_arc(&self) -> PointArc
