Struct EncoderState 

pub struct EncoderState { /* private fields */ }

Heapless ordinary Base64 encoder state.

The state retains at most two incomplete input bytes and one four-byte encoded quantum. It intentionally has no cleanup destructor; secret transforms use a separate state type.

Implementations

impl EncoderState

pub fn update( &mut self, input: &[u8], output: &mut [u8], ) -> Result<Step, OperationError>

Accepts an input prefix and writes as much encoded output as fits.

pub fn finish(&mut self, output: &mut [u8]) -> Result<Step, OperationError>

Emits the canonical final tail and completes the current message.

pub fn reset(&mut self)

Resets the state for one unrelated message.

pub fn clear(&mut self)

Clears retained ordinary input and output through the reviewed wipe boundary, then resets the state for reuse.

This is explicit best-effort cleanup. It cannot clear bytes already returned to a caller or copies retained by an input source, allocator, register, cache, swap device, or crash dump.

pub const fn source_position(&self) -> usize

Returns the absolute number of input bytes accepted since reset.

pub const fn buffered_input_len(&self) -> usize

Returns raw input bytes retained until the next complete quantum.
