pub struct WormArchiver { /* private fields */ }Expand description
Builds and signs the per-segment integrity manifest that backs WORM mode.
The archiver owns no store handle: the backend uploads the objects, hands the archiver what it observed for each, and gets back manifest bytes plus a receipt. Keeping the IO in the backend and the cryptography here makes the manifest logic testable without an object store.
Debug shows the key id and never the key. The archiver holds live
private-key material, and a Debug that walked into it would put that key
in every log line that formats a backend.
Implementations§
Source§impl WormArchiver
impl WormArchiver
Sourcepub fn new(signer: Option<Arc<FileEd25519Signer>>) -> Self
pub fn new(signer: Option<Arc<FileEd25519Signer>>) -> Self
An archiver that signs with signer, or leaves manifests unsigned when
signer is None.
Sourcepub fn from_config(cfg: &WormConfig) -> Result<Self, WormError>
pub fn from_config(cfg: &WormConfig) -> Result<Self, WormError>
Loads the signing key that cfg names, if it names one.
§Errors
WormError::SigningKey when a key path is set without a key id (or
vice versa), or the file is not a PKCS#8 Ed25519 key.
Sourcepub fn seal(
&self,
metadata: &RemoteLogSegmentMetadata,
objects: Vec<ObjectEntry>,
) -> Result<SealedManifest, WormError>
pub fn seal( &self, metadata: &RemoteLogSegmentMetadata, objects: Vec<ObjectEntry>, ) -> Result<SealedManifest, WormError>
Seals one segment copy: builds the manifest, chains it, and signs it.
objects must list every object the copy wrote, in the order it wrote
them.
§Errors
WormError::MissingChainStamp when the broker did not stamp a chain
position on metadata — a WORM backend refuses to write an unchained,
and therefore unverifiable, manifest.
WormError::MalformedChainRecord when the stamp is present but does
not decode, and WormError::Codec when the manifest does not
serialise.

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();§fn bright_black(&self) -> Painted<&T>

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute] value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();§fn rapid_blink(&self) -> Painted<&T>

§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi [Quirk] value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>

§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition] value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
