This create allows a Holochain project to easily use the anchors pattern for creating links. This is still a work in progress and feedback would be appreciated.
Add the following to your zomes cargo toml.
holochain_anchors = "0.2"
Add the anchor entry def to your zome.
rust
#[entry_def]
fn anchor_def() -> ValidatingEntryType {
holochain_anchors::anchor_definition()
}
Link from the ANCHOR_TYPE
```rust
links: [
from!(
holochainanchors::ANCHORTYPE,
linktype: "mylinktype",
validationpackage: || {
hdk::ValidationPackageDefinition::Entry
},
validation: |_validation_data: hdk::LinkValidationData| {
Ok(())
}
)
]
Create an anchor and link an entry to it.
If the anchor already exists then it will use the existing anchor.
rust
let myentry = Entry::App(
"myentry".into(),
MyEntry{
content: "somecontent".into()
}.into()
);
let address = hdk::commitentry(&myentry)?;
let anchoraddress = holochainanchors::createanchor("myanchortype".into(), "myanchor".into())?;
hdk::linkentries(&anchoraddress, &address, "mylinktype", "myanchor")?;
Get all the links on that anchor.
rust
let anchoraddress = holochainanchors::createanchor("myanchortype".into(), "myanchor".into())?;
hdk::utils::getlinksandloadtype(&anchoraddress, LinkMatch::Exactly("mylink_type"), LinkMatch::Any)
```
