Enum SourcePolicy 

pub enum SourcePolicy {
    LocalFirst,
    S3First,
    RemoteOnly,
    LocalOnly,
}

Per-image override for the registry resolution chain order.

The puller’s default chain is LOCAL store → local CACHE → shared S3 tier → the ref’s own registry (URL) → last-resort default registry. A spec/compose entry may pin a different behavior; None on ImageSpec == Self::LocalFirst.

Variants

LocalFirst

Default chain order (local store → cache → S3 → URL → fallback).

S3First

Probe the shared S3 tier BEFORE the local in-process cache (otherwise the default order). Useful when S3 is the fleet’s canonical warm pool.

RemoteOnly

Skip every local/cached/S3 source — always resolve from the ref’s own registry (or the configured default registry for a bare name).

LocalOnly

Resolve ONLY from local sources (local store + cache); never touch S3, the network, or the default-registry fallback. A miss is an error.

Trait Implementations

impl Clone for SourcePolicy

fn clone(&self) -> SourcePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SourcePolicy

impl Debug for SourcePolicy

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

Formats the value using the given formatter.

impl Default for SourcePolicy

fn default() -> SourcePolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SourcePolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SourcePolicy

impl PartialEq for SourcePolicy

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SourcePolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
