Struct DatumDecoder 

pub struct DatumDecoder(/* private fields */);

Decoder for the Datum encoding layer.

Trait Implementations

impl Clone for DatumDecoder

fn clone(&self) -> DatumDecoder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DatumPipe for DatumDecoder

type Input = char

type Output = DatumChar

fn feed<F: FnMut(DatumOffset, DatumChar) -> DatumResult<()>>( &mut self, at: DatumOffset, char: Option<char>, f: &mut F, ) -> DatumResult<()>

Feeds in I, and you may some amount of O. If None is passed, EOF happened. Beware that EOF offsets will ‘skip’ the function for future stages, so transforming offsets here is not okay. The primary purpose of the offset output is to ensure offsets reliably point at the start of an output, rather than the end; this can be used for various useful purposes. Because of that, offsets may “jump backwards” if it’s useful to do so (this happens in the tokenizer).

fn feed_iter_to_vec<S: IntoIterator<Item = Self::Input>, V: Extend<Self::Output>>( &mut self, target: &mut V, source: S, eof: bool, ) -> DatumResult<()>

Feeds into a vec or similar from a slice. Offsets are automatically managed, starting from 0 and increasing by 1 for each input element. Can also automatically trigger EOF.

fn compose<P: DatumPipe<Input = Self::Output>>( self, other: P, ) -> DatumComposePipe<Self, P>

where Self: Sized,

Composes with another pipeline.

impl Debug for DatumDecoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DatumDecoder

fn default() -> DatumDecoder

Returns the “default value” for a type.

impl PartialEq for DatumDecoder

fn eq(&self, other: &DatumDecoder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
