Struct SourceId 

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

Stable identity for a source, for cache keying and lineage. Assigned by the engine; a SubRange/decrypted/overlay source records this so a block cache can account by identity rather than by accident of equal offsets.

Implementations

impl SourceId

pub const ROOT: SourceId

The base/root source of a lineage when no engine has assigned one yet.

pub const fn new(id: u64) -> Self

Wrap a raw id.

pub const fn get(self) -> u64

The raw id.
