Enum AnchorGrain 

pub enum AnchorGrain {
    Span,
    File,
    Tree,
    Url,
    Entity,
}

The granularity of the artifact reference an anchor carries.

span / file / tree select within a path-shaped namespace; url selects a web resource; entity selects another mem’s entity. The medium-capability matrix (crate::binding::medium_capabilities) decides which grains a given medium’s namespace can support — a mismatch (e.g. span on a url-namespace medium) refuses typed at validation.

Variants

Span

File

Tree

Url

Entity

Implementations

impl AnchorGrain

pub const WIRE_VALUES: &'static [&'static str]

Every wire string, in declaration order.

pub fn as_wire(&self) -> &'static str

Stable wire form.

pub fn from_wire(s: &str) -> Option<Self>

Inverse of Self::as_wire; None for an unknown string.

pub fn supported_by_namespace(&self, anchor_namespace: &str) -> bool

Whether this grain can be expressed in the medium’s declared anchor namespace (the anchor_namespace string from the E2 capability matrix: path / path+commit / entity / url).

• span / file / tree require a path-shaped namespace (path or path+commit);
• url requires the url namespace;
• entity requires the entity namespace.
