Trait winnow::stream::StreamIsPartial

pub trait StreamIsPartial: Sized {
    type PartialState;

    // Required methods
    fn complete(&mut self) -> Self::PartialState;
    fn restore_partial(&mut self, state: Self::PartialState);
    fn is_partial_supported() -> bool;

    // Provided method
    fn is_partial(&self) -> bool { ... }
}

Marks the input as being the complete buffer or a partial buffer for streaming input

See Partial for marking a presumed complete buffer type as a streaming buffer.

Required Associated Types

type PartialState

Whether the stream is currently partial or complete

Required Methods

fn complete(&mut self) -> Self::PartialState

Mark the stream is complete

fn restore_partial(&mut self, state: Self::PartialState)

Restore the stream back to its previous state

fn is_partial_supported() -> bool

Report whether the Stream is can ever be incomplete

Provided Methods

fn is_partial(&self) -> bool

Report whether the Stream is currently incomplete

Object Safety

This trait is not object safe.
