Struct Provenance 

pub struct Provenance {
    pub kind: String,
    pub uri: Option<String>,
    pub range: Option<String>,
    pub digest: Option<String>,
    pub method: Option<String>,
    pub by: Option<String>,
}

One link in a frame’s provenance chain, ordered closest-to-source first.

Fields

kind: String

e.g. “file”, “derivation”, “episode”.

uri: Option<String>

range: Option<String>

digest: Option<String>

method: Option<String>

by: Option<String>

Implementations

impl Provenance

pub fn is_file_provenance(&self) -> bool

Whether this link addresses bytes a host could independently re-read.

pub fn has_well_formed_digest(&self) -> bool

Whether the digest, if present, matches the grammar in SPEC.md §F5.

Absent counts as not well-formed: for file provenance the digest is what makes tamper-detection possible at all, and treating “no digest” as acceptable is how the guarantee stayed decorative for so long.

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Provenance

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Provenance

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Provenance

fn eq(&self, other: &Provenance) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
