Struct OwnedChannelPlan 

pub struct OwnedChannelPlan { /* private fields */ }

A channel plan that owns its tables.

Query it through with_plan, which lends the tables to a borrowed ChannelPlan for the duration of one call.

Implementations

impl OwnedChannelPlan

pub fn from_plan(plan: &ChannelPlan<'_>) -> Self

Copies a borrowed plan into owned storage.

This is how a host takes a published region and holds onto it: the result is independent of where the original tables lived, so one type serves both a named region and a plan built here.

The copy describes the one plan it was taken from. The plans a join selects between, which only the published CN470-510 plans name, point at other published plans and are not carried over.

Arguments

• plan - the plan to copy.

Returns

An owned copy answering exactly what the original does.

Examples

use pamoja_lora::region::{OwnedChannelPlan, Region};

let held = OwnedChannelPlan::from_plan(Region::Eu868.plan());
assert_eq!(held.with_plan(|plan| plan.rx2()), (869_525_000, 0));

pub fn with_plan<R>(&self, query: impl FnOnce(&ChannelPlan<'_>) -> R) -> R

Lends the owned tables to a borrowed plan for one query.

The row pointers a plan needs are assembled on the stack for the call, so nothing outlives it and the storage stays here.

Arguments

• query - what to ask the plan.

Returns

Whatever the query returned.

Examples

use pamoja_lora::region::{OwnedChannelPlan, Region};

let held = OwnedChannelPlan::from_plan(Region::In865.plan());
let name = held.with_plan(|plan| plan.name.to_owned());
assert_eq!(name, "IN865");
