Enum PoolIdentifier 

pub enum PoolIdentifier {
    Address(Ustr),
    PoolId(Ustr),
}

Protocol-aware pool identifier for DeFi liquidity pools.

This enum distinguishes between two types of pool identifiers:

• Address: Used by V2/V3 protocols where pool identifier equals pool contract address (42 chars: “0x” + 40 hex)
• PoolId: Used by V4 protocols where pool identifier is a bytes32 hash (66 chars: “0x” + 64 hex)

The type implements case-insensitive equality and hashing for address comparison, while preserving the original case for display purposes.

Variants

Address(Ustr)

V2/V3 pool identifier (checksummed Ethereum address)

PoolId(Ustr)

V4 pool identifier (32-byte pool ID as hex string)

Implementations

impl PoolIdentifier

pub fn new_checked<T: AsRef<str>>(value: T) -> Result<Self>

Creates a new PoolIdentifier instance with correctness checking.

Automatically detects variant based on string length:

• 42 characters (0x + 40 hex): Address variant
• 66 characters (0x + 64 hex): PoolId variant

Errors

Returns an error if:

• String doesn’t start with “0x”
• Length is neither 42 nor 66 characters
• Contains invalid hex characters
• Address checksum validation fails (for Address variant)

pub fn new<T: AsRef<str>>(value: T) -> Self

Creates a new PoolIdentifier instance.

Panics

Panics if validation fails.

pub fn from_address(address: Address) -> Self

Creates an Address variant from an alloy Address.

Returns the checksummed representation.

pub fn from_pool_id_bytes(bytes: &[u8]) -> Result<Self>

Creates a PoolId variant from raw bytes (32 bytes).

Errors

Returns an error if bytes length is not 32.

pub fn from_pool_id_hex<T: AsRef<str>>(hex: T) -> Result<Self>

Creates a PoolId variant from a hex string (with or without 0x prefix).

Errors

Returns an error if the string is not valid 64-character hex.

pub fn inner(&self) -> Ustr

Returns the inner identifier value as a Ustr.

pub fn as_str(&self) -> &str

Returns the inner identifier value as a string slice.

pub fn is_address(&self) -> bool

Returns true if this is an Address variant (V2/V3 pools).

pub fn is_pool_id(&self) -> bool

Returns true if this is a PoolId variant (V4 pools).

pub fn to_address(&self) -> Result<Address>

Converts to native Address type (V2/V3 pools only).

Returns the underlying Address for use with alloy/ethers operations.

Errors

Returns error if this is a PoolId variant or if parsing fails.

pub fn to_pool_id_bytes(&self) -> Result<[u8; 32]>

Converts to native bytes array (V4 pools only).

Returns the 32-byte pool ID for use in V4-specific operations.

Errors

Returns error if this is an Address variant or if hex decoding fails.
