Enum Adapter 

pub enum Adapter {
    File,
    S3,
    B2,
    Gcs,
    External {
        name: String,
    },
}

Which snapdir storage adapter a store URL resolves to.

The four named variants are the adapters shipped in-process by the Rust port (no subprocess). Adapter::External is any third-party adapter, dispatched out-of-process to a snapdir-<name>-store binary via the emit-command shim.

Variants

File

Built-in file:// backend (local directory).

S3

Built-in s3:// backend (native AWS SDK).

B2

Built-in b2:// backend (native AWS SDK against Backblaze).

Gcs

Built-in gs:// backend (native Google Cloud Storage SDK). Scheme gs, adapter name gcs.

External

A third-party adapter resolved to a snapdir-<name>-store binary on PATH. name is the adapter name (the store protocol verbatim).

Fields

name: String

The adapter name (equal to the store URL’s protocol).

Implementations

impl Adapter

pub fn name(&self) -> &str

The adapter’s canonical name (gs resolves to gcs, matching the oracle’s special case).

pub fn store_binary(&self) -> String

The snapdir-<name>-store binary this adapter corresponds to.

For the built-in adapters this is the helper binary the original implementation would have shelled out to (one per file/s3/b2 adapter, plus the gcs adapter via the gs→gcs special case). The Rust port serves the built-ins in-process and only spawns the binary for Adapter::External.

pub fn is_builtin(&self) -> bool

Whether this adapter is served in-process by the Rust port (true) or dispatched to a third-party binary via the shim (false).

Trait Implementations

impl Clone for Adapter

fn clone(&self) -> Adapter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Adapter

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

Formats the value using the given formatter.

impl Eq for Adapter

impl PartialEq for Adapter

fn eq(&self, other: &Adapter) -> 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.
