isBuffer :: a → Boolean
Evaluates whether the given value is of type UInt8Array
import isBuffer from 'deep-waters/isBuffer';
const x = new Uint8Array([21, 31]);
isBuffer(x); // → true
isBuffer(20); // → false
isBuffer("hello"); // → false
isBuffer(undefined"); // → false
isBuffer, like any other type validator, is mostly used in composed validators:
import isString from 'deep-waters/isString';
import matchesPattern from 'deep-waters/matchesPattern';
const isEmail = compose(
isBuffer is built on top of ofClass validator and rely on Object.prototype.toString to check on the received value type in order to avoid typeof weird behaviours and encouraging a runtime strict type validation.
isBuffer is actually a semantic shortcut to isUInt8Array.
