Struct PartReader 

pub struct PartReader<'r, R: Read> { /* private fields */ }

Available on crate feature std only.

One part of a MultipartReader: read it like a file.

Read reports a parse error as std::io::Error with kind InvalidData and the FormError as its source.

Implementations

impl<R: Read> PartReader<'_, R>

pub fn head(&self) -> &OwnedPartHead

The part’s head, copied when the part started.

pub fn text(&mut self) -> Result<String, FormError>

Reads the rest of the part and checks it as text (its charset, else the _charset_ field before it, else UTF-8), bounded by max_value_bytes for file parts too.

Errors

Every multipart error; Encoding { InvalidUtf8 | UnsupportedCharset }; Limit { ValueLength }.

pub fn skip(&mut self) -> Result<u64, FormError>

Discards the rest of the part and returns its data length.

Errors

Every multipart error.

pub fn save(&mut self, store: &Store) -> Result<StoredFile, FormError>

Available on crate feature fs only.

Streams a file part into store.

Errors

Every multipart error; Io, Store, Limit { Disk }.

Trait Implementations

impl<R: Read> Debug for PartReader<'_, R>

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

Formats the value using the given formatter.

impl<R: Read> Read for PartReader<'_, R>

fn read(&mut self, out: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Reads all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Reads all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_, u8>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact( &mut self, cursor: BorrowedCursor<'_, u8>, ) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Reads the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.

fn read_array<const N: usize>(&mut self) -> Result<[u8; N], Error>

where Self: Sized,

🔬This is a nightly-only experimental API. (read_array)

Read and return a fixed array of bytes from this source.

fn read_le<T>(&mut self) -> Result<T, Error>

where T: FromEndianBytes, Self: Sized,

🔬This is a nightly-only experimental API. (read_le)

Read and return a type (e.g. an integer) in little-endian order.

fn read_be<T>(&mut self) -> Result<T, Error>

where T: FromEndianBytes, Self: Sized,

🔬This is a nightly-only experimental API. (read_le)

Read and return a type (e.g. an integer) in big-endian order.
