Enum Chain 

pub enum Chain {
    Solana {
        reference: String,
    },
    Evm {
        reference: String,
    },
}

A blockchain network, identified by namespace and reference per CAIP-2.

Variants

Solana

Solana — Ed25519 signing.

Reference is the genesis hash prefix (e.g. 5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp for mainnet).

Fields

reference: String

Evm

EVM-compatible chain — secp256k1 / EIP-191 signing.

Reference is the integer chain ID as a string (e.g. "8453" for Base).

Fields

reference: String

Implementations

impl Chain

pub fn solana_mainnet() -> Self

Solana mainnet.

pub fn base() -> Self

Base (EVM chain ID 8453).

pub fn tempo() -> Self

Tempo mainnet (EVM chain ID 4217).

pub fn tempo_testnet() -> Self

Tempo testnet (EVM chain ID 42431).

pub fn caip2(&self) -> String

Format as a CAIP-2 chain identifier string.

Examples: "solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp", "eip155:8453".

pub fn from_caip2(s: &str) -> Result<Self, JwtError>

Parse a CAIP-2 chain identifier string.

pub fn namespace(&self) -> &str

Returns the CAIP-2 namespace ("solana" or "eip155").

pub fn jwt_algorithm(&self) -> JwtAlgorithm

Returns the JWT algorithm for this chain.

Trait Implementations

impl Clone for Chain

fn clone(&self) -> Chain

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Chain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Chain

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Chain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Chain

fn eq(&self, other: &Chain) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Chain

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Chain

impl StructuralPartialEq for Chain
