Struct ContentUnavailable 

pub struct ContentUnavailable {
    pub path: Option<Vec<u8>>,
    pub reason: String,
}

What: Something the provider could not read. Option<Vec<u8>> is “a path, or nothing” (nothing when the tracked-path listing itself failed); String is owned UTF-8 text. Why: The engine reports this as content-unavailable: the policy is intact, its input is missing.

In TS you’d write (pseudocode):

type ContentUnavailable = { path?: Uint8Array; reason: string };

Fields

path: Option<Vec<u8>>

The path whose bytes could not be read, or nothing for the listing.

reason: String

The provider’s explanation.

Trait Implementations

impl Clone for ContentUnavailable

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentUnavailable

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

Formats the value using the given formatter.

impl Eq for ContentUnavailable

impl From<ContentUnavailable> for PlanError

What: Lift an unreadable-content failure into a planning failure. impl Trait for Type gives a type the methods a trait requires. Why: Lets the planner write content.candidate_bytes(path)?.

In TS you’d write (pseudocode):

const failure: PlanError = { kind: 'content-unavailable', error };

fn from(error: ContentUnavailable) -> PlanError

Wrap the unreadable-content failure.

impl PartialEq for ContentUnavailable

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

Equality operator ==.

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

Inequality operator !=.
