Struct ColumnAssignment 

pub struct ColumnAssignment {
    pub column: String,
    pub index: i16,
    pub retired: bool,
}

One source column’s pinned replicate index, as the API’s register response reports it (and as stream metadata persists it under replicates.assignments). Sync services assign each value’s replicate_index by looking its source column up here.

Fields

column: String

index: i16

retired: bool

The source no longer sends this column. The index stays reserved and remains the column’s identity should it reappear.

Implementations

impl ColumnAssignment

pub fn from_metadata(metadata: &Value) -> Option<Vec<Self>>

The pinned mapping a stream’s metadata carries, when the API has authored one. None on metadata written by an API that predates pinning.
