    pub via: Option<Expr>,
}

A single entry in a reads: or writes: signal list.

Fields

cfg: Vec<Attribute>

#[cfg(...)] attributes attached to this entry.

path: Path

index: Option<Expr>

observed: Option<Ident>

Present when the entry is marked observed.

beat: Option<Ident>

Present when the entry is marked beat.

veto: Option<Ident>

Present when the entry is marked veto: this writer holds one contributor slot of a VetoGate.

via: Option<Expr>

The accessor expression supplied by observed via <expr>.
