Struct Snapshot 

pub struct Snapshot { /* private fields */ }

The IDs of one world, each with a fingerprint of its content.

Implementations

impl Snapshot

pub fn from_world(world: &World, limits: &Limits) -> Result<Self, Error>

The snapshot of a loaded source tree. The world is already in memory, so limits bound the snapshot built from it.

Errors

Returns Error::TooManyIds if the world has more IDs than limits allow, or Error::Invalid if a document of the world cannot be read again, which a world that loaded never has.

pub fn from_pack(pack: &Pack, limits: &Limits) -> Result<Self, Error>

The snapshot of a content pack. The pack is fully verified first, as Pack::verify does, and its IDs are then read through Pack::visit_identities one row at a time; reading stops as soon as the pack has more IDs than limits allow.

Errors

Returns Error::TooManyIds past the limit, or Error::Pack if the pack does not verify or SQLite fails.

pub const fn side(&self) -> &Side

Where the snapshot came from.

pub fn contains(&self, kind: Kind, id: &str) -> bool

Whether the world has ID id of kind.

pub fn object_plane(&self, uid: &str) -> Option<&str>

The plane the object with uid is on.

pub fn ids(&self, kind: Kind) -> impl Iterator<Item = &str>

The IDs of kind, in byte order.
