Struct Uid 

pub struct Uid(pub u128);

A 128-bit id (a UUID’s bits, a hash), spelled as 32 lower-case hex digits: @doc:0123456789abcdef0123456789abcdef.

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl NamedType for Uid

Stored as its hex text everywhere (a tool shows a uid).

const NAME: &'static str = "uid"

What tools know it by: "color", "date".

type Stored = String

What it’s stored as.

fn to_stored(&self) -> String

Its stored form.

fn from_stored(s: String) -> Option<Uid>

The value stored holds, if it’s a valid one.

impl Ord for Uid

fn cmp(&self, other: &Uid) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Uid

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Uid

fn partial_cmp(&self, other: &Uid) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl RefId for Uid

const EXPECTED: Expected = Expected::Uid

What an id of this type looks like, for messages.

fn parse(spelled: &str) -> Option<Uid>

The id spelled is, if it’s one of this type.

fn spell(&self) -> Cow<'_, str>

As written after @kind:.

impl Schema for Uid

fn shape() -> Shape

What the format looks like.

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

Reads v. Problems go to cx at its current path; None when the value couldn’t be read (the problem is in cx).

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<Uid>

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 pack(&self, p: &mut Packer)

Packs itself into a frame (crate::frame): its binary form as bytes, unless the type packs itself (derived ones and plain types do).

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

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.
