Functions

f Hasher.anyDeepHasher	Returns a Hasher instance that hashes any value, and traverses into an object or array to hash its elements.
f Hasher.anyFlatHasher	Returns a Hasher instance that hashes any value, but never traverses into an object or array to hash its elements. In those cases it will use toString.
f Hasher.anyJsonStringHasher	Returns a Hasher instance that hashes any value by hashing the string resulting from applying JSON.stringify to the value.
f Hasher.anyShallowHasher	Returns a Hasher instance that hashes any value, but only traverses into an object or array to hash its elements one level deep. After one level, it will use toString.
f Hasher.anyToStringHasher	Returns a Hasher instance that hashes the string representation of any value
f Hasher.arrayHasher	Returns a Hasher that hashes arrays of elements by sampling the array and using the given `itemHasher` to hash the sampled elements.
f Hasher.bigintHasher	Returns a Hasher instance that hashes bigints.
f Hasher.booleanHasher	Returns a Hasher instance that hashes booleans.
f Hasher.createValueOfHasher	Returns a Hasher instance that hashes the `.valueOf` value of the given object using the given `valueHasher` for instances of given `cls` class.
f Hasher.dateHasher	Returns a Hasher instance that hashes Dates.
f Hasher.defaultHasher
f Hasher.numberHasher	Returns a Hasher instance that hashes numbers, including 'special' values like NaN and infinities.
f Hasher.objectDeepHasher	Returns a Hasher instance that hashes objects of key type K and value type V. If a value if an object or array, it will recursively hash its values.
f Hasher.objectHasher	Returns a Hasher instance that hashes objects of key type K and value type V.
f Hasher.objectShallowHasher	Returns a Hasher instance that hashes objects of key type K and value type V. If a value if an object or array, it will convert those values to a string.
f Hasher.streamSourceHasher	Returns a Hasher instance that hashes any StreamSource limited to a certain amount of elements to prevent haning on infinite streams.
f Hasher.stringCaseInsensitiveHasher
f Hasher.stringHasher	Returns a Hasher instance for string values.
f Hasher.tupleSymmetric	Returns a Hasher that will return equal hash values for values in a tuple regardless of their order, and uses the given `hasher` function to hash the tuple elements.

interface Hasher

import { type Hasher } from "https://deno.land/x/rimbu@0.14.0/hashed/common/hasher.ts";

Interface used to hash objects for hashed collections.

Type Parameters

Methods

isValid(obj: unknown): obj is UK

Returns true if this hasher can be applied to the given obj object.

hash(value: UK): number

Returns the 32-bit hash code for the given value.
