Module winnow::stream

Stream capability for combinators to parse

Stream types include:

• &[u8] and Bytes for binary data
• &str (aliased as Str) and BStr for UTF-8 data
• Located can track the location within the original buffer to report spans
• Stateful to thread global state through your parsers
• Partial can mark an input as partial buffer that is being streamed into
• [Custom stream types][crate::_topic::stream]

Structs

BStr

Improved Debug experience for &[u8] UTF-8-ish streams

BitOffsets

Iterator for bit stream ((I, usize))

Bytes

Improved Debug experience for &[u8] byte streams

Located

Allow collecting the span of a parsed token

Partial

Mark the input as a partial buffer for streaming input.

Stateful

Thread global state through your parsers

Enums

CompareResult

Result of Compare::compare

Traits

Accumulate

Abstracts something which can extend an Extend. Used to build modified input slices in escaped_transform

AsBStr

Helper trait for types that can be viewed as a byte slice

AsBytes

Helper trait for types that can be viewed as a byte slice

AsChar

Transforms a token into a char for basic string parsing

Compare

Abstracts comparison operations

ContainsToken

Check if a token in in a set of possible tokens

FindSlice

Look for a slice in self

Location

Number of indices input has advanced since start of parsing

Offset

Useful functions to calculate the offset between slices and show a hexdump of a slice

ParseSlice

Used to integrate str’s parse() method

SliceLen

Abstract method to calculate the input length

Stream

Core definition for parser input state

StreamIsPartial

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

ToUsize

Helper trait to convert numbers to usize.

UpdateSlice

Convert a Stream into an appropriate Output type

Type Definitions

Str

UTF-8 Stream
