    Count(Vec<Part>),
    Each(Vec<Part>),
    Create {
        source: u32,
        target: u32,

}

One call of the links interface.

Variants

Count(Vec<Part>)

Number of links matching the restriction.

Each(Vec<Part>)

Every link matching the restriction, ordered by index.

Create

Creates a link.

Fields

source: u32

target: u32

Update

Points an existing link at a new source and target; an update that would duplicate an existing link merges into it instead.

Fields

index: u32

source: u32

target: u32

Delete(u32)

Deletes a link, and every link that still refers to it.

GetName(u32)

The name of a link.

SetName(u32, String)

Names a link.

GetByName(String)

The link with a name.

RemoveName(u32)

Removes the name of a link.
