Struct Parser 

pub struct Parser { /* private fields */ }

Available on crate features http and multipart and std only.

Sans-IO parser of a multipart/form-data body.

Drive it with step: on Event::NeedInput hand it the next body chunk with feed, or call set_eof once the body is over. It never reads, waits or buffers part data, so it serves a server reading a form as much as a proxy rewriting one as it streams by (see Encoder).

An error is final: every later step returns it again.

Implementations

impl Parser

pub const MAX_HEAD_SIZE: usize = MAX_HEAD_SIZE

Upper bound for the header block of a single part, in bytes.

pub const MAX_HEADERS: usize = MAX_HEADERS

Upper bound for the number of header lines of a single part.

pub fn new(boundary: &Boundary) -> Parser

Create a parser for a body framed by boundary.

pub fn wants_input(&self) -> bool

Whether more input would be put to use: false once the close delimiter is read or parsing failed.

pub fn feed(&mut self, chunk: Bytes)

Hand over the next body chunk, only after Event::NeedInput.

pub fn set_eof(&mut self)

Signal that the body has no more chunks.

pub fn step(&mut self) -> Result<Event, ParseError>

Advance to the next event.

Trait Implementations

impl Debug for Parser

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

Formats the value using the given formatter.
