Enum UnderlyingType 

#[non_exhaustive]
pub enum UnderlyingType {
    Coin,
    Index,
    Premarket,

    HkEquity,
    KrEquity,
    Fx,
    Other(String),
}

What a contract’s underlying is, from exchangeInfo. The values seen on 2026-10-07; Binance’s docs give no list.

Variants (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.

Coin

Index

Premarket

Commodity

Equity

CnEquity

HkEquity

KrEquity

Fx

Other(String)

A value this version of the SDK does not recognise, kept verbatim. Sending it in a request passes the string through unchanged.

Build it with from_wire or FromStr, never directly: Other holding a known spelling serialises as the named variant does, but does not compare equal to it.

Implementations

impl UnderlyingType

pub const ALL: &'static [Self]

Every variant this SDK knows, in declaration order. Other is not among them: it holds whatever else the server sends.

pub fn as_str(&self) -> &str

The wire spelling.

pub fn from_wire(s: &str) -> Self

Parse a wire spelling; anything unrecognised becomes Other.
