Enum sp_rpc::number::NumberOrHex[−][src]

pub enum NumberOrHex {
    Number(u64),
    Hex(U256),
}

Expand description

A number type that can be serialized both as a number or a string that encodes a number in a string.

We allow two representations of the block number as input. Either we deserialize to the type that is specified in the block type or we attempt to parse given hex value.

The primary motivation for having this type is to avoid overflows when using big integers in JavaScript (which we consider as an important RPC API consumer).

Variants

Number(u64)

The number represented directly.

Hex(U256)

Hex representation of the number.

Implementations

impl NumberOrHex

pub fn into_u256(self) -> U256
