Class Base64Abstract

constructor

• new Base64(): Base64

• Returns Base64

Abstract Readonly alphabet

Abstract asPadded

• asPadded(padded): Base64

• Returns this Base64 encoding with required padding, if padded is true.

  Parameters

  • padded: boolean

  Returns Base64

decodeDigit

• decodeDigit(c): number

• Returns the 7-bit quantity represented by the base-64 digit c.

  Parameters

  • c: number

  Returns number

  Throws

  Error if c is not a valid base-64 digit.

encodeDigit

• encodeDigit(b): number

• Returns the Unicode code point of the base-64 digit that encodes the given 7-bit quantity.

  Parameters

  • b: number

  Returns number

Abstract isDigit

• isDigit(c): boolean

• Returns true if the Unicode code point c is a valid base-64 digit.

  Parameters

  • c: number

  Returns boolean

Abstract isPadded

• isPadded(): boolean

• Returns true if this base-64 encoding requires padding.

  Returns boolean

parse

• parse<O>(input, output): Parser<O>

• Parses the base-64 (7-bit ASCII) encoded input, and writes the decoded bytes to output, returning a Parser continuation that knows how to parse any additional input.

  Type Parameters

  • O

  Parameters

  • input: Input

  • output: Output<O>

  Returns Parser<O>

parseUint8Array

• parseUint8Array(input): Parser<Uint8Array>

• Parses the base-64 (7-bit ASCII) encoded input, and writes the decoded bytes to a growable array, returning a Parser continuation that knows how to parse any additional input. The returned Parser [[Parser.bind binds]] a Uint8Array array containing all parsed base-64 data.

  Parameters

  • input: Input

  Returns Parser<Uint8Array>

parser

• parser<O>(output): Parser<O>

• Returns a Parser that decodes base-64 (7-bit ASCII) encoded input, and writes the decoded bytes to output.

  Type Parameters

  • O

  Parameters

  • output: Output<O>

  Returns Parser<O>

uint8ArrayWriter

• uint8ArrayWriter(): Writer<Uint8Array, unknown>

• Returns a Writer that, when fed an input Uint8Array, returns a continuation that writes the base-64 (7-bit ASCII) encoding of the input Uint8Array.

  Returns Writer<Uint8Array, unknown>
• uint8ArrayWriter(input): Writer<unknown, Uint8Array>

• Returns a Writer continuation that writes the base-64 (7-bit ASCII) encoding of the input byte array.

  Parameters

  • input: Uint8Array

  Returns Writer<unknown, Uint8Array>

writeQuantum

• writeQuantum<T>(output, c1, c2, c3, c4): Output<T>

• Decodes the base-64 digits c1, c2, c3, and c4, and writes the 8 to 24 bit quantity they represent to the given output.

  Type Parameters

  • T

  Parameters

  • output: Output<T>

  • c1: number

  • c2: number

  • c3: number

  • c4: number

  Returns Output<T>

  the continuation of the output.

writeUint8Array

• writeUint8Array(output, input): Writer<unknown, unknown>

• Writes the base-64 (7-bit ASCII) encoding of the input Uint8Array to the output, returning a Writer continuation that knows how to write any remaining output that couldn't be immediately generated.

  Parameters

  • output: Output<unknown>

  • input: Uint8Array

  Returns Writer<unknown, unknown>

Static standard

• standard(padded?): Base64

• Returns the Base64 encoding with the standard alphabet, and required padding, if isPadding is true.

  Parameters

  • Optional padded: boolean

  Returns Base64

Static url

• url(padded?): Base64

• Returns the Base64 encoding with the url and filename safe alphabet, and required padding, if padded is true.

  Parameters

  • Optional padded: boolean

  Returns Base64
