Struct SnapshotId 

pub struct SnapshotId(/* private fields */);

Content-addressed snapshot identifier.

Invariant: always the string "sha256:" followed by exactly 64 lower-case hex characters. Enforced by SnapshotId::from_hash. Custom Deserialize validates the invariant via from_prefixed, rejecting malformed inputs.

Implementations

impl SnapshotId

pub fn from_hash(hex: &str) -> Result<Self, VcsError>

Construct from a raw hex digest (without the "sha256:" prefix).

Returns Err(VcsError::InvalidSnapshotId) if hex is not exactly 64 lower-case hex characters.

pub fn from_prefixed(s: &str) -> Result<Self, VcsError>

Construct from a full prefixed string ("sha256:<hex64>").

pub fn as_str(&self) -> &str

Returns the full string including the "sha256:" prefix.

pub fn hex(&self) -> &str

Returns only the 64-character hex digest (without prefix).
