Implementations

impl<M: Mirror> MirrorWriter<'_, M>

pub fn row(&mut self, key: u64) -> Option<M::Writer<'_>>

pub fn leave(&mut self, row: u32)

Row row no longer filled.

pub fn member(&self) -> Option<&str>

The family member written now (a dimension), when its space is a family’s.

pub fn scopes<S: Schema>(&self) -> impl Iterator<Item = S> + '_

What the declarations asked it to cover.

pub fn due_scopes<S: Schema>(&self) -> impl Iterator<Item = S> + '_

The scopes due this turn (the others only kept as keys).

pub fn keep_keys(&mut self, live: &[(u64, Option<u64>)])

Makes the key space’s keys live (a mod’s own key space).

pub fn wants(&self, fields: u64) -> bool

Whether any of fields is due.
