Struct HashConfig 

pub struct HashConfig {
    pub algorithm: HashAlgorithm,
    pub seed: u64,
}

Hash configuration

For WDP compliance, use HashConfig::wdp_compliant() which uses xxHash3 with the standard WDP seed.

Fields

algorithm: HashAlgorithm

The hash algorithm to use (only xxHash3 for WDP)

seed: u64

Seed for the hash

Default is 0x000031762D706477 per WDP specification.

Implementations

impl HashConfig

pub fn new(seed: u64) -> Self

Create a new hash config with custom seed

pub fn wdp_compliant() -> Self

Create a WDP-compliant config (xxHash3 + WDP seed)

This is the standard configuration per WDP Part 5.

pub fn with_seed(seed: u64) -> Self

Create a config with a custom seed (for testing/isolation)
