Struct Stream 

pub struct Stream<T> { /* private fields */ }

A list of T kept written: its body in the binary form, its strings its own.

Implementations

impl<T: Schema> Stream<T>

pub fn writer() -> StreamWriter<T>

Writes items one by one (StreamWriter::push).

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = T> + '_

The items, read as they’re asked for; it stops at one it can’t read.

pub fn to_vec(&self) -> Vec<T>

Every item, read now.

pub fn bytes_len(&self) -> usize

How many bytes it takes.

Trait Implementations

impl<T> Clone for Stream<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Stream<T>

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

Formats the value using the given formatter.

impl<T> Default for Stream<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Schema> From<Vec<T>> for Stream<T>

fn from(items: Vec<T>) -> Self

Converts to this type from the input type.

impl<T: Schema> FromIterator<T> for Stream<T>

fn from_iter<I: IntoIterator<Item = T>>(items: I) -> Self

Creates a value from an iterator.

impl<T> PartialEq for Stream<T>

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

Equality operator ==.

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

Inequality operator !=.

impl<T: Schema> Schema for Stream<T>

fn read(v: &ValueRef<'_>, cx: &mut Reader<'_>) -> Option<Self>

The slow way (a text file, a value): read whole, then written.

fn pack(&self, p: &mut Packer)

In a frame it’s a list, as its shape says.

fn shape() -> Shape

What the format looks like.

fn write(&self) -> Value

The value, as the format writes it.

fn encode(&self, w: &mut Writer)

Writes itself in the binary form, straight — Schema::write’s value encoded, unless the type knows better (derived ones do).

fn decode(d: &mut Decoder<'_>) -> Option<Self>

Reads itself from the binary form, straight; None when it isn’t what Schema::encode writes — then read_bytes reads the slow way, which says what’s wrong. Through a value unless the type knows better (derived ones do).

fn unpack(u: &mut Unpacker<'_>) -> Option<Self>

Reads itself out of a frame; None if the bytes aren’t what Schema::pack writes.

fn absent() -> Option<Self>

The value of a field that isn’t there — None: the field is required.

fn skip(&self) -> bool

Whether a struct leaves this field out when writing it.

fn pack_list(items: &[Self], p: &mut Packer)

A list of these packed: a count, then each one (floats raw).

fn unpack_list(u: &mut Unpacker<'_>) -> Option<Vec<Self>>

A list of these out of a frame.

fn encode_list(items: &[Self], w: &mut Writer)

A list of these written straight (numbers pack theirs).

fn decode_list(d: &mut Decoder<'_>) -> Option<Vec<Self>>

A list of these read straight.
