Enum Domain

pub enum Domain {
    VariableLength,
    FixedLength,
}

The hasher Domain differentiates between the modes of hashing.

The main purpose of declaring the domain is to prevent collisions between different types of hashing by introducing defining differences in the way the hash function’s internal state (e.g. a sponge state’s capacity) is initialized.

Variants

VariableLength

The VariableLength domain is used for hashing objects that potentially serialize to more than RATE number of field elements.

FixedLength

The FixedLength domain is used for hashing objects that always fit within RATE number of fields elements, e.g. a pair of Digests.

Trait Implementations

impl Debug for Domain

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

Formats the value using the given formatter.

impl PartialEq for Domain

fn eq(&self, other: &Domain) -> 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 Eq for Domain

impl StructuralPartialEq for Domain
