Struct RelationContext 

pub struct RelationContext {
    pub at_token: Vec<RelationReading>,
    pub phase_of: Vec<u16>,
    pub value_history: Vec<WindowProfile>,
    pub period: Option<u16>,
}

The related context at every token.

Fields

at_token: Vec<RelationReading>

One reading per token index. A whitespace token carries the reading of the significant token before it.

phase_of: Vec<u16>

Per token index, the token’s phase of the dominant period - its index among the significant tokens modulo the period - or u16::MAX for an insignificant token or a stream with no period.

value_history: Vec<WindowProfile>

Per token index, the fold over the values bound to earlier occurrences of the token’s key: for each earlier occurrence that is the left operand of a binding punctuation (=, :), the reading of the right operand. Identity for an unkeyed token, a first occurrence, or a key never bound before.

period: Option<u16>

The dominant token-kind period the phase fold is keyed on, when the stream has one.
