Enum OptionStreamCapability 

Source 
#[non_exhaustive]
pub enum OptionStreamCapability {
    None,
    SymbolOnly {
        verified: bool,
    },
    ChainQuotes {
        verified: bool,
    },
}
Expand description

Contract-level streaming: does the provider stream option-contract quotes/Greeks that overlay onto a chain (docs/03-data-providers.md §2, §8)?

verified: false means “the stream exists upstream but ChainView has no recorded fixture yet, so snapshot polling is the supported live path” — a cell flips to verified: true only in the PR that lands its fixture (§8 gate).

#[non_exhaustive]; default None.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

None

No contract-level stream (Alpaca — its WebSocket carries only the underlying).

§

SymbolOnly

Individual symbols only, with no chain of its own — usable purely as an overlay onto an external chain source (standalone dxlink).

Fields

§verified: bool

Whether a recorded fixture proves the decode (§8 gate).

§

ChainQuotes

Contract quotes/Greeks that overlay onto an assembled chain.

Fields

§verified: bool

Whether a recorded fixture proves the decode (§8 gate).
