Struct base64ct::Encoder

pub struct Encoder<'o, E: Variant> { /* private fields */ }

Stateful Base64 encoder with support for buffered, incremental encoding.

The E type parameter can be any type which impls Encoding such as [Base64] or [Base64Unpadded].

Internally it uses a sealed Variant trait which is an implementation detail of this crate, and leverages a blanket impl of Encoding.

Implementations

impl<'o, E: Variant> Encoder<'o, E>

pub fn new(output: &'o mut [u8]) -> Result<Self, Error>

Create a new decoder for a byte slice containing contiguous (non-newline-delimited) Base64-encoded data.

pub fn encode(&mut self, input: &[u8]) -> Result<(), Error>

Encode the provided buffer as Base64, writing it to the output buffer.

Returns

• Ok(bytes) if the expected amount of data was read
• Err(Error::InvalidLength) if there is insufficient space in the output buffer

pub fn finish(self) -> Result<&'o str, Error>

Finish encoding data, returning the resulting Base64 as a str.
