Implementations

impl Base64

pub fn encode<'s, 'd>(
    &self,
    src: &'s [u8],
    dst: OutBuf<'d>
) -> Result<&'d mut [u8], Error>

Encodes src and writes to dst.

Errors

This function returns Err if:

• The length of dst is not enough.

pub fn decode<'s, 'd>(
    &self,
    src: &'s [u8],
    dst: OutBuf<'d>
) -> Result<&'d mut [u8], Error>

Decodes src and writes to dst.

Errors

This function returns Err if:

• The length of dst is not enough.
• The content of src is invalid.

pub fn decode_inplace<'b>(
    &self,
    buf: &'b mut [u8]
) -> Result<&'b mut [u8], Error>

Decodes buf and writes inplace.

Errors

This function returns Err if:

• The content of buf is invalid.

When this function returns Err, the content of buf should be considered as fully broken.

impl Base64

pub fn encode_to_boxed_str(&self, src: &[u8]) -> Box<str>

Encodes src and returns Box<str>

Panics

This function panics if:

• The encoded length of src is greater than isize::MAX

pub fn decode_to_boxed_bytes(&self, src: &[u8]) -> Result<Box<[u8]>, Error>

Decodes src and returns Box<[u8]>

Errors

This function returns Err if:

• The content of src is invalid.

pub fn forgiving_decode_inplace(buf: &mut [u8]) -> Result<&mut [u8], Error>

Forgiving decodes buf and writes inplace.

impl Base64

pub const STANDARD: Self = Self { kind: Base64Kind::Standard, padding: true, }

Standard charset with padding.

pub const STANDARD_NO_PAD: Self = Self { kind: Base64Kind::Standard, padding: false, }

Standard charset without padding.

pub const URL_SAFE: Self = Self { kind: Base64Kind::UrlSafe, padding: true, }

URL-safe charset with padding.

pub const URL_SAFE_NO_PAD: Self = Self { kind: Base64Kind::UrlSafe, padding: false, }

URL-safe charset without padding.

pub const fn encoded_length(&self, n: usize) -> usize

Calcuates the encoding length.

Panics

This function panics if any of the conditions below is not satisfied:

• n <= isize::MAX

pub const fn charset(&self) -> &[u8; 64]

Returns the character set used for encoding.

Trait Implementations

impl Debug for Base64
