Struct AnchorInput 

pub struct AnchorInput {
    pub artifact: Option<String>,
    pub grain: Option<String>,
    pub class: Option<String>,
    pub at_version: Option<AnchorVersion>,
    pub hash: Option<String>,
    pub hash_stability: Option<String>,
    pub derived_from: Option<Vec<String>>,
    pub binding: Option<String>,
    pub source: Option<String>,
}

A permissive wire-shaped anchor element as it arrives on a mutation’s anchors[] parameter. All fields are optional / string-typed so an unknown class or grain surfaces as a typed AnchorValidationError with recovery detail rather than an opaque serde failure. Call Self::validate to obtain a strict Anchor.

Fields

artifact: Option<String>

grain: Option<String>

class: Option<String>

at_version: Option<AnchorVersion>

hash: Option<String>

hash_stability: Option<String>

derived_from: Option<Vec<String>>

binding: Option<String>

source: Option<String>

Implementations

impl AnchorInput

pub fn validate( &self, medium: Option<(&str, &str)>, ) -> Result<Anchor, AnchorValidationError>

Validate this wire element into a strict Anchor, or refuse typed.

medium — the resolving medium’s (type_name, anchor_namespace) pair, when the mutation resolved one. When Some, the grain is checked against the namespace (the capability-matrix refusal); when None (no medium context — a manually-authored anchor), the namespace check is skipped and only the vocabulary + hash-semantics rules apply.

Rules enforced (each a typed AnchorValidationError):

• class present and known;
• grain present and known;
• artifact reference present and non-empty;
• a hash is supplied only on a hash-bearing class;
• hash stability, when supplied, is a known wire string (defaults to stable when absent);
• grain supported by the medium’s namespace (when medium given).
