Struct BorrowLedger 

pub(crate) struct BorrowLedger {
    next: u64,
    held: Vec<Lease>,
}

Every claim currently held on a world’s components.

Fields

next: u64

The id the next holder is given.

held: Vec<Lease>

Implementations

impl BorrowLedger

pub(crate) fn next_group(&mut self) -> u64

The id the next holder files its claims under.

pub(crate) fn claim( &mut self, group: u64, type_id: TypeId, name: &'static str, mode: Mode, rows: Rows, origin: &'static Location<'static>, )

Register a claim, or panic when it overlaps one held by another holder.

A holder asking again for a component it already holds over the same rows is not a conflict: that is what a second pass over one archetype does.

pub(crate) fn release(&mut self, group: u64)

Drop every claim one holder made.
