Struct Declared 

pub struct Declared { /* private fields */ }

Fields of a mirror asked for: written at the rate asked while this lives, read in place; dropped, what only it asked for stops.

Implementations

impl Declared

pub fn new( spec: &MirrorSpec, wanted: u64, rate: Rate, ) -> Result<Declared, Diagnostic>

Asks for wanted fields of spec (a bit each, in field order) at rate.

pub fn scoped( spec: &MirrorSpec, wanted: u64, rate: Rate, scope: Option<Vec<u8>>, ) -> Result<Declared, Diagnostic>

Declared::new covering scope only (the mirror’s scope type as Yog Data: a BlockScope…).

pub fn rows(&self) -> impl Iterator<Item = u32> + '_

The rows its provider fills that hold a key now.

pub fn row_of(&self, key: u64) -> Option<u32>

key’s row.

pub fn key_of(&self, row: u32) -> Option<u64>

Row row’s key.

pub fn get<T: Cell>(&self, field: usize, row: u32) -> Option<T>

Field field’s value at row row (None: not asked for, no row).

Trait Implementations

impl Drop for Declared

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
