v1 source realm

Package wrap is version 1 of the "wrapping versions" upgrade pattern (pattern A of the exploration; see ../README.md).

Readme View source

gno.land/r/moul/x/upgrade/wrap/v1

Version 1 of the wrapping versions upgrade pattern (pattern A). Keeps its own counter and adds v0's on read. Both versions stay writable, so the two paths report different totals and neither is authoritative.

z_wrap_filetest.gno walks that divergence step by step.

See the pattern and the exploration.

Overview

Package wrap is version 1 of the "wrapping versions" upgrade pattern (pattern A of the exploration; see ../README.md).

v1 owns a counter of its own and ADDS v0's on read. Both versions stay live and independently writable, so the two paths report different totals and neither is authoritative. That is the pattern's defining trade-off: no migration, no downtime, no coordination, and no single answer either.

Functions 3

func Get

Action
1func Get() int
source

Get returns v0's counter plus this version's own. Reading across the version boundary is a plain non-crossing call: no realm is entered as a writer, so this stays queryable from vm/qeval and from Render.

func Inc

crossing Action
1func Inc(cur realm, n int)
source

Inc adds n to this version's own counter. It does NOT touch v0.
